A car of mass 940 kg is traveling over the top of a hill as shown in the figure below.
1. If the hill has a radius of curvature of 34 m and the car is traveling at 13 m/s, what is the normal force among the hill and the car at the top of the hill?
2. If the driver increases her speed sufficiently, the car will leave the ground at the top of the hill. What is the speed needed to make that happen?
