A 21.0 kg shopping cart is moving with a velocity of 8.0 m/s. It strikes a 11.0 kg box that is initially at rest. They stick together and continue moving at a new velocity. Assume that friction is negligible.
1. What was the momentum of the shopping cart before the collision?
2. What was the momentum of the box before the collision?
3. What is the velocity of the combined shopping cart-box wreckage after the collision?
