When Tom struck Beth’s jump shot 25m into the stands with a force of 100N, the work done by him is 2500J.
<h3>What do you mean by Work done?</h3>
Work done may be defined as the process of transferring energy from one source to the other. It is the outcome of force and displacement.
From the above definition, W = F×d
W = 100N × 25m ⇒ 2500N/m
∴ Workdone, W = 2500J.
