The Figure Shows An Initially Stationary Block Of Mass

A force probe is attached to the block and the center of the disk, as shown above. How does the gravitational force, FgA, exerted on satellite A from the planet compare with the gravitational force, FgB, exerted on satellite B from the planet? The ramp makes an angle θ with the horizontal, as shown in Figure 1. An experiment is conducted in which a cart travels across a horizontal surface and collides with a wall. Which of the following graphs shows how the centripetal acceleration behaves as a function of time? Which of the following diagrams represents the final velocities for Block X and Block Y after the collision if the collision is elastic? The system is open and the net external force is zero A student performs an experiment in which a ball travels in a perfect circle. The figure shows an initially stationary block of mass. Point P Mgh +1/2mv^2 Point Q mgh+1/2mv^2 Objects X and Y are connected by a string of negligible mass and suspended vertically over a pulley of negligible mass, creating an Atwood's machine, as shown in the figure. The student uses one end of a string to attach the object while the other end is connected to a force sensor that allows the student to change the tension on the string, as shown in the figure.

If an astronaut wants to stand on one of the asteroids and experience the largest net gravitational force, where should the astronaut stand? A graph of the kinetic energy of the block as a function of the distance the spring is compressed is shown that was collected from experimental data. Accelerometer Force sensor Accelerometer and Force sensor A 2 kg object is released from rest near the surface of a planet with a negligible atmosphere. The figure shows an initially stationary block dna. The subsequent momentum change (magnitude only) of the two skaters will be ____. Sal does this: Coefficient of static friction= 50/N. Point P is the highest point in the rock's trajectory, and point Q is level with the initial position of the rock.

5M, as shown in Figure 2. 27 kg) • (-280 cm/s) / (0. 0 m rough section of the surface where friction is not negligible, and the coefficient of kinetic friction between the block and the rough section Hk is 0. Which of the following statements are correct regarding the motion of the block? Is Student X's reasoning correct, and why or why not? A graph of the force exerted by the spring on the object as a function of the position of the object is shown. That makes sense minus mu MG minus P. Okay so just continuing with this PICO sine phi plus M. U. K< Ko, because the force of friction removes mechamcal energy from the block-ramp-Earth system on its way up the ramp and back down the ramp. The force is the only force exerted on the object and is applied in the direction of the object's velocity. A - 0-> Fgravity The moon has a mass of 1 x 10^22 kg, and the gravitational field strength at a distance R from the planet is 0. And so is P co sign of five. The centripetal acceleration of the moon is most nearly 20m/s^2 In which of the following situations is the gravitational force the dominant force?

The two masses eventually is correct regarding the momentum of the system of mass M, and the system of mass M, and M2 in terms of their momenta? Block X and block Y are made of the same material. D - 75 N A block of mass M is attached to a modified Atwood machine and is accelerated upward at 3a by a constant force F0. 6, 36) A student must determine the work done on an object when an external force is exerted on it after it travels a specific distance. Immediately after the impulse of the explosion, a photogate timer measures the cannon to recoil backwards a distance of 6. Yet even if the masses of the two objects are different, the momentum change of the two objects (mass • velocity change) will be equal in magnitude. A block of mass M on an inclined surface is attached to a spring of negligible mass, as shown. AND The change in momentum of the block from the applied force is 5 kg⋅ms A student must perform an experiment in which two objects travel toward each other and collide so that the data collected can be used to show that the collision is elastic within the acceptable range of experimental uncertainty. In the experiment to find the objects inertial mass, the student uses a spring scale to pull the object, starting from rest, across a horizontal surface with a constant applied force such that the frictional forces are considered to be negligible.

After the collision, Block Y travels in the positive direction with velocity vY while Block X remains nearly at rest. I need to substitute in for P. Now I'm going to factor out MG. You know what I'm gonna know I'm going to factor out empty and then I'm going to distribute the 0. The spring is compressed and the carts are placed next to each other. After the force is applied to the block, the block travels with a speed of 5 ms. Block Y has a mass of 1kg and a speed of 3m/s. The system of the two objects is released from rest, and a graph of the system's center of mass velocity as a function of time is shown. Solving Explosion Momentum Problems. Did not overcome the frictional force. Well we already determined that if it is not accelerating in this normal direction there must be zero net forces on it But if it is stationary as a whole then there must be zero net forces in the parallel component too So there must be some force counteracting this 49 N that wants to take it down the slope So there must be some force counteracting the component of gravity that wants to accelerate it down the slope And the question is what is this force? The same tension force T is exerted on both blocks, and the block of mass M experiences an acceleration a, in the downward direction when released from rest. Which data from the graph should the student use to determine the direction of the net force exerted on the cart and the direction of the change in momentum of the cart from the time intervals of A to B?

The force is exerted on the block in the same direction as the block's displacement while the force is exerted. What is the new tangential speed of the ball? Using the table means that you can use the same problem solving strategy for both collisions and explosions. How much work does the spring do on the object as it pushes the object upward until the object is no longer in contact with the spring? Since the cannon was moving at constant speed during this time, the distance/time ratio will provide a post-explosion speed value. A graph of the force that object X exerts on object Y is shown.

The Figure Shows An Initially Stationary Blocks

So now we've got to go to kinetic friction. The speed of the car will remain the same, and the car will travel in the opposite direction. The kinetic energy increases because the gravitational force due to Earth does positive net work on the system. Coefficiente of cinetic friction= 49/N. In an experiment, a student measures the centripetal force exerted on the block when placed at various distances from the center of the disc while the tangential speed of the edge of the disc remains constant. Both the planet and the star accelerate, because each object exerts a force on the other object. Which of the following claims can be made by relating one of Newton's laws of motion to an object that travels in uniform circular motion?

Consider the trial in which the ramp is at a 20° angle with the horizontal. Which of the following claims about the situation is correct? Both rocks fall for several seconds before landing on the ground directly below the cliff. In this setup, the coefficient of static friction between the table and the block resting upon it must be at least 1. What is the net force on Planet Y, and what reasoning supports this claim? 16 meters per second. Which of the following equations for the conservation of momentum could a student use to help determine the speed vf of each block after the collision? A - Measure the mass of the system using a balance, activate the fan, measure the distance traveled by the system at a known time by using a stopwatch, and repeat the experiment for several trials with different objects added to the carriage. Which of the following sets of data could represent the collision for cart X and cart Y? Which two of the following claims are correct about the accelerations associated with the planet, star, and planet-star system? A. is dependent upon the mass and velocities of the two cans. 4 m/s 6 m/s A 9000 kg rock slides on a horizontal surface with negligible friction at 3 m/s toward a 3000 kg rock that is at rest, as shown in Figure 1.

After the force has been applied for a time Δt, the speeds of blocks A and B are vA and vB, respectively. Determine the area bound by the curve and the horizontal axis. The student uses the spring scale to pull the cart starting from rest along a horizontal surface such that the reading on the spring scale is always constant. C Block X of mass 2kg travels across a horizontal surface toward block Y of unknown mass that is initially at rest. Well, this block is completely stationary. Which of the following indicates the direction of the velocity of Skater X and the direction of the velocity of the center of mass of the two-skater system after the push? An applied force is exerted on the object, and a graph of the magnitude of the applied force as a function of time is shown. After the car travels for a time t = 5 seconds, the speed of the car is 25 m/s. The block exerts a force on the string. 5F0 to the right, because the gravitational force from Planet Y is greater than the gravitational force from Planet X. In experiment two, the object is pulled along a horizontal surface with a spring scale such that the force reading on the spring scale remains constant while a motion detector is used to measure the instantaneous speed of the object as it is pulled. B. is dependent upon the velocities of the two cans (but not their mass). It passes through a 2. They push off on each other in order to set each other in motion.
