Chapter 6, Problem 6.81(choose chapter or problem)
A 1200-kg car is being driven up a 5.0 hill. The frictional force is directed opposite to the motion of the car and has a magnitude of f 524 N. A force is applied to the car by the road and propels the car forward. In addition to these two forces, two other forces act on the car: its weight and the normal force directed perpendicular to the road surface. The length of the road up the hill is 290 m. What should be the magnitude of , so that the net work done by all the forces acting on the car is 150 kJ?
