Question

Problem 8.42 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 cars engine. The work done by friction is -2.91x105 J the work done by the engine is 6.64x105 J Part A Find the change in the cars kinetic energy from the bottom of the hill to the top of the hill Xb b AK Submit My Answers Give Up incorrect, Try Again; 5 attempts remaining Provide Feedback Continue

    A 1750kg car starts at the bottom of a 20m tall hill traveling at 15 m/s. During the trip up the hill, air resistance does -50 kJ of work on the car, and friction does an additional -120 kJ of work on the car. What is the minimum amount of work the engine must do in order for the car to reach the top of the hill?
