1. The problem statement, all variables and given/known data
An escalator at a mall lifts passengers 6m. The escalator has to be able to lift 50-75kg people at one time up the lift. The time to make it to the top is 40s. What must the power rating of the escalator be?
2. Relevant equations
w=fd
p=w/t
3. The attempt at a solution
w=6f
