Question

A 1500-kg elevator moves upward with constant speed through a vertical distance of 25 m. How much work was done by the tension in the elevator cable

Answer 1

Answer:

367500Joules

Explanation:

Work done is expressed as;

Work done = force × distance

Force = mass × acceleration due to gravity

Force = 1500×9.8

Force = 14700N

Given

Distance covered = 25m

Workdone = 14700×25

Work done = 367500Joules

Hence the work done by the tension in the elevator cable is 367500Joules
