Question

On a building site, a crane lifts a load of bricks. The lifting force is 2750N and the bricks are raised to a height of 9.0m. Calculate the work done by the crane in lifting the bricks.

Answer 1

Answer:

the work done in raising the load is 24,750 J

Explanation:

Given;

load lifted by the crane with a force, F = 2750 N

height through which the load was raised, h = 9.0 m

The work done by the crane in raising the load is calculated as;

W =  F x h

W = 2750 x 9

W = 24,750 J

Therefore, the work done by the crane in raising the load is 24,750 J
