(a) List the forces exerted on the spring-cart system of Figure 15.1 right after it is released, and draw a freebody diagram for each object in the system.

(b) Which of these forces do work on the system as it oscillates?

(c) As the hand pushes on the cart and compresses the spring, is the work done by the cart on the spring positive, negative, or zero?

(d) How does the work done by the cart on the spring compare with the work done by the spring on the cart?
