Question

A forklift was used to lift a 750 kg. oil drum 18 m straight up into the air to store on a shelf. If it does it in 28 seconds, Calculate the work and power exerted by the forklift.

W= J

P= watts

Answer 1

Step-by-step explanation:

Given parameters:

Mass of forklift = 750kg

Height of lift = 18m

Time taken = 28s

Unknown:

Work done = ?

Power = ?

Solution;

The work done by the forklift is given as:

Work done = mass x acceleration due to gravity x height

Work done = 750 x 9.8 x 18 = 132300J

Power is the rate at which work is done;

Power =
`(work done )/(time)`

Insert the parameters and solve;

Power =
`(132300)/(28)` = 4725W
