Work =force×displacement=15×2=30joules. ... box of 15 kg from the ground to a height of 2 metre calculate the work done by the Coolie on the box ...
or
Given, mass, m = 15 kg, distance, i = 2m, g = 9.8 ${{ms}^{2}}$, W = ?
Now, force applied, F w mg = 15 x 9.8 = 147 N
.’. Work done, W= Fx s= 147 X 2 = 294 N
