Question

A porter lift a luggage of $15kg$ from the ground and puts it on her head $2m$ above the ground. Calculate the work done by her on the luggage? Take $g=10m{s}^{-2}$

Answer 1

Step 1, Given data

Mass of the luggage = $15kg$

Height up to which it is lifted = $2m$

Step 2, Finding the work done

We know,

When an object is lifted up the work done is given as

$Work=m\times g\times h$

Putting all the values

$Work=15\times 10\times 2$

Or, Work done = $300J$

Hence total work done is $300J$
