1. The graph shown describes the force acting on an object moving along the x-axis. If the average speed of the object is v avg = 8.00 m/s, what average power P does the force F deliver to the object as it moves from x = 0 m to x = 40 m?

2. A toy car is released from rest on a track at a height h and encounters a vertical loop of radius R as shown. What is the minimum height h for which the car will successfully complete the vertical loop?
