Question

In a stair case power lab, if you have the height of the steps, the time and the mass, how do you find the force and the power?

Answer 1

The force needed to go up the steps at constant speed equals the weight, M g. The energy required to climb a vertical distance H is M g H, and the power required is that energy divided by the time needed to climb.
