A 60g ball of clay is thrown horizontally at 10m/s toward a 1.8kg block sitting at rest on a frictionless hi surface. The clay hits and sticks to the block.
A.) What is the speed of the block and clay right after the collision?
B.) What impulse does the clay exert on the block?
C.) What impulse does the block exert on the clay?
