Problem 49P

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 −3.11 × 105 J; the work done by the engine is + 6.44 × 105 J. Find the change in the car’s kinetic energy from the bottom of the hill to the top of the hill.

ANSWER:

Step 1 of 2:

In this question, we have two non conservative force acting on car (1)  friction force and the (2)  force generated by car’s engine

We need to find the change in car’s kinetic energy from bottom to top of the hill

Data given
