Two carts on a frictionless track are initially held together by a compressed spring. Cart A has mass m; Cart B has mass 3m. After the spring is released, Cart A is observed to move with speed 3.0m/s to the right. (a) Determine the speed of Cart B. (b) State whether the impulse delivered to each cart is greater for Cart A, greater for Cart B, or the same, and justify your answer in one sentence.
