An escalator in a shopping centre carries people up through a height h at a vertical speed of
v, but you’re in a hurry when you step onto it, so you climb the moving steps (each with a
height of h
) at a rate of n steps/s. Determine:
4.1 the amount of chemical energy converted into mechanical energy by your leg muscles
s
during your escalator ride, given that your mass is m;
4.2 the work the escalator motor does on you;
4.3The total amount of work done by your legs and the escalator in getting you to the top.
