Question

A car engine applies a force of 65 kN, how much work is done by the engine as it pushed a car a distance of 75 m?

Answer 1

Given,

Force applied is 65kN.

The distance travelled is 75 m.

We know work done is given by:

W=Force.distance travelled.

Thus,

`\begin{gathered} W=65*75kN-m \\ \Rightarrow W=4875\text{ kJ} \end{gathered}`

The answer is 4875 kJ
