1. A 23-g bullet traveling 230 m/sm/s penetrates a 4.9 kg block of wood and emerges cleanly at 175 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?
2. A 11800 kg railroad car travels alone on a level frictionless track with a constant speed of 24.5 m/s. A 6800 kg load, initially at rest, is dropped onto the car. What will be the car's new speed?
