A 5.00-kg box is pushed 5.00 m up a plane that is inclined at 30.0^o with the horizontal. The coefficient of kinetic friction between the box and the plane is 0.200. The change in potential energy of the box is approximately

Question

Quizplus · Accepted Answer

The change in potential energy is given by mgh, where h is the vertical height. The height can be found using h = 5.00 m * sin(30.0°) = 2.5 m. Thus, the change in potential energy is 5.00 kg * 9.81 m/s² * 2.5 m = 122.625 J, approximately 123 J.
