Question

In one eight-hour workday, a forklift operator at a particular distribution warehouse lifts a total of 100,000 N of boxes. Each box must be lifted to a height of 1.5 m and carried an average of 10 m to the shipping dock. What is the net work done against gravity?

Answer 1

Answer:

150000 J

Explanation:

Only the work that is used to lift the boxes up by 1.5 m is counted against gravity. The work that is used to move 10m to the dock is not.

This work done to lift up by 1.5m is the product of force lifted F = 100 000 N and the vertical distance in height h = 1.5m

W = F*h = 100000*1.5 = 150000 J
