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 3.0 gg bullet, fired horizontally at a speed of 390 m/sm/s , goes completely through the block, emerging at a speed of 220 m/sm/s .

What is the speed of the block immediately after the bullet exits?
