Question

A boy pushes a cart through a distance of $100m$ by applying a force of $50N$. How much work is done by the boy?

Answer 1

Step 1: Given data

Force, $F=50N$

Distance, $s=100m$

Work done, $W=?$ (To be calculated)

Step 2: Calculating the work done

Applying, $Workdone\left(W\right)=force\left(F\right)\times displacement\left(s\right)$

By putting the given values in a formula, we get

$$\begin{gathered} W=F\times s \\ W=50N\times 100m \\ \therefore W=5,000J \end{gathered}$$

Hence, the work done by the boy is $5,000J$
