Part A An assembled system consists of cart A of inertia mA, cart B of inertia mB, and a spring of What is the final speed of the cart A? negligible inertia, clamped together so that the fully compressed spring is aligned between the front end Express your answer in terms of the variables mA, MB, Es, and vi. of cart B and the back end of cart A. The internal energy of the system, stored in the compressed spring, is Es. The system is put on a low-friction AEQ ? track and given a small shove so that it moves to the right at speed vi, with cart A in front. Once the system is moving, the clamp is released (by remote VA control, so that the motion of the system as a whole is not affected in any way). As the spring expands, the carts move apart.
