A 1010-kg car is being driven up a 9.28 ° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of 536 N. A force F 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 W and the normal force FN directed perpendicular to the road surface. The length of the road up the hill is 302 m. What should be the magnitude of F, so that the net work done by all the forces acting on the car is 170 kJ?

A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...

A 1250 kg car drives up a hill that is 16.2 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is -2.91 times 10^5 J; the work done by the engine is 6.64 times 10^5 J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.
