Two initially stationary carts, A and B, are pushed across a frictionless horizontal surface by the same horizontal force. Cart B is heavier than Cart A, but both are pushed for the same time. After the push, which cart has the greater final momentum?
(a)They have the same final momentum
(b)Cart B
(c) Cart A
After the push, which cart has the greater final kinetic energy?
(a)Cart A
(b)Cart B
(c)They have the same final kinetic energy
