A package of mass m is released from rest at a warehouse loading dock and slides down the h = 2.0 m high, frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2m2m, from the bottom of the chute. Suppose the packages stick together. What is their common speed after the collision? Suppose the collision between the packages is perfectly elastic. To what height does the package of 2m mass mm rebound?

A 7,300-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 8 m/s. Compute how much kinetic energy was "lost" in this inelastic collision.  answer using J (JOULE)

In a railroad accident, a boxcar weighing 200 kN and traveling at 2.00 m/s on horizontal track slams into a stationary caboose weighing 440 kN. The collision connects the caboose to the boxcar. How much energy is transferred from kinetic energy to other forms of energy in the collision?

Two blocks with masses m1 = 1.4kg and m2 = 4.6kg are at rest on a frictionless surface with a compressed spring between them. When the blocks are let go, block 1 is observed to have a velocity of 4.4m/s to the left. What is the speed of block 2?

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?

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

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.

A 7.17 g pellet is shot horizontally from a BB gun at a speed of 24.8 m/s into a 28.7 g wooden block. The wooden block is attached to a spring and lies on a frictionless table. If the collision is inelastic and the spring constant k = 16.0 N/m, what is the maximum compression of the spring?

Gayle runs at a speed of 3.65 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 48.0 kg, the sled has a mass of 5.45 kg and her brother has a mass of 30.0 kg. m/s
