A Porter lifts a luggage of 15 kg from the ground and puts it on his head 1.5 m above the ground. Calculate the work done on the luggage.

Open in App

Solution

We know that,
Work done = change in potential energy= mgh.
where m is the mass lifted, g is the acceleration due to gravity, h is the height lifted.
Therefore,
W = mgh = 15×9.8×1.5
W = 220.5 J.
