Work problem 20


A car drives up a slope. At the bottom of the slope, its kinetic energy is equal to 245 kJ, and at the top of the slope, its kinetic energy is equal to 192 kJ. While driving uphill, its potential energy increases by 136 kJ.

  • What is the change in the car's kinetic energy?

  • Does the car receive or transmit work while driving?

  • Calculate the work that the car exchanges with its surroundings while driving uphill.
