A 83.2 g marble moving at 10.2 m/s approaches and collides head-on with a stationary 41.8 g marble. Assuming that the collision is elastic, what are the corresponding kinetic energy of each marble?
A spring pushes against two horizontal carts that are held together by a thread on a frictionless surface. Cart A is 1.5-kg and Cart B is 4.5-kg. The thread is then burned, releasing the stored energy of the spring and the carts move away from each other. The Cart A moves with a velocity of 27cm / s to the left. What is the velocity of the Cart B, in cm / s ?
In a circus act, a 55.5 kg clown with 2.5 m/s horizontal velocity jumps into the air and is caught by a 72.5 kg clown who was initially at rest. The clown is sitting on a sheet of ice, and moves off at some new velocity, after the two clowns are stuck together. How much kinetic energy is lost during this process?

In the figure below, a 3.1 kg box of running shoes slides on a horizontal frictionless table and collides with a 1.8 kg box of ballet slippers initially at rest on the edge of the table, at height = 0.40 m. The speed of the 3.1 kg box is 5.0 m/s just h before the collision. If the two boxes stick together because of packing tape on their sides, what is their kinetic energy just before they strike the floor? ។ h
The ballistic pendulum is a device to measure the speed of a bullet using conservation of energy and momentum. A 20 g bullet is fired horizontally into a 1.1 kg wood block hanging from a 1.2-m-long string. The bullet embeds itself into the block, and the block then swings out to an angle of 35°. A. How high does the block of wood go relative to its initial height when its hanging straight down? B. What is the increase in gravitational potential energy of the wood block at its maximum height? C. Use conservation of energy to determine the speed of the block just after the bullet strikes it. D. Use conservation of momentum to determine the speed of the bullet right before it strikes the block.
A 100-kg particle moves with an initial velocity of (4.0i, - 6.0j) m/s. If its velocity changes to v = (3.0i – 8.0j) m/s by the action of a force, determine The net work done on the particle. What principle would you use to solve this problem? The impulse on the particle. True or False: Impulse is equal to the rate of change of momentum.
