A 21.0 kg shopping cart is moving with a velocity of 4.0 m / s. It strikes a 7.0 kg box that is initially at rest. They stick together and continue moving at a new velocity. Assume that friction is negligible.
What was the momentum of the shopping cart before the collision? 168 kg dot m/s 84.0 kg dot m/s 44.0 kg dot m/s 0 kg dot m/s
What was the momentum of the box before the collision? 84.0 kg dot m/s 0 kg dot m/s 168 kg dot m/s 44.0 kg dot m/s
What is the velocity of the combined shopping cart/box wreckage after the collision? 4.0 m/s 7.64 m/s 2.6 m/s 0 m/s
