Chapter 10, Problem 63GP

* A 0.5-kg low-friction cart is moving at constant speed of 1.7 m/s to the left along a horizontal table toward a relaxed spring with k = 120 N/m that is fixed at me left end to a wall. At t = 0, the front of the cart is 20 cm from the free end of the spring The cart hits the spring, and the spring compresses and expands, making the car move to the right with the same speed as the initial speed. (a) Sketch me situation. Determine the clock reading at the moment when the front (left end) of me cart passes the position where it was at t = 0 again. (b) Choose the cart and the spring as a system and represent the process using energy and momentum bar charts. (Hint: Think about which part of the cart's motion can be treated as vibrational motion.)
