Two 0.50-kg carts resting on a low-friction track and connected by a spring are pushed toward each other. The left cart is pushed with a force of 10 N over a distance of 0.10 m, and the right cart is pushed with a force of 5 N over a distance of 0.04 m. Assume the spring has negligible inertia. You can convince yourself that the center of mass moved to the right by 0.03 m. Calculate the change in center of mass kinetic energy of the system consisting of the two carts and the spring.

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
