A hill is 200 m long and makes an angle of 12 $\degree$with the horizontal. As a 50-kg jogger runs up the hill, how much work does gravity do on the jogger?

Question

Quizplus · Accepted Answer

The work done by gravity is negative because it acts in the opposite direction to the jogger's movement. The vertical height (h) can be found using h = 200 m * sin(12°). The work done by gravity is W = mgh = 50 kg * 9.8 m/s² * h, which calculates to approximately -20,000 J.
