Q. A 13 g bullet traveling 224m/s penetrates a 2.0 kg block of wood and emerges cleanly at 164 m/s. If the block is stationary on a frictionless surface while hit, how fast does it move after the bullet emerges?
Q. A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface. Upon release, the mass travels across the surface until it encounters a rough incline. The mass moves up incline and stops at a height of 1-m above the horizontal surface.
