A thin block of soft wood with a mass of 0.0800 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 564 m/s at a block of wood and passes completely through it. The speed of the block is 16.0 m/s immediately after the bullet exits the block.

(a) Determine the speed of the bullet as it exits the block.
__ m/s

(b) Verify by calculating the initial and final kinetic energies of the system.

Ki =

__ J

Kf =

__ J

1. On a frictionless horizontal air table, puck A (with mass 0.252 kgkg ) is moving toward puck B (with mass 0.375 kgkg ), which is initially at rest. After the collision, puck A has velocity 0.122 m/sm/s to the left, and puck B has velocity 0.651 m/sm/s to the right. Calculate ΔKΔKDeltaK, the change in the total kinetic energy of the system that occurs during the collision. 2. A 2.5 kgkg block of wood sits on a frictionless table....

A bullet with a mass ?b=12.7 g is fired into a block of wood at velocity ?b=261 m/s. The block is attached to a spring that has a spring constant ? of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass of the wooden block.
