7. A 1300 kg car drives up a 17 m high hill (the elevation of the hill is 17 meters). During the drive two nonconservative forces do work on the car: the force of friction and the force generated by the car’s engine. The work done by friction adds 331 kJ to the internal energy. The work done by the engine is 634 kJ. (a) What is the change in the car’s kinetic energy? (b) If the car started up...

A car of mass 1100 kg starts from rest at sea level and climbs a hill of height 50.0 m. At the top of the hill, the car has a speed of 25.0 m/s, and at this instant, the driver shuts off the engine of the car. The car then coasts down the other side of the hill to height of 15.0 m above sea level. Assume that friction and air resistance are negligibly small. a) (6 pts) How much...

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.
