Question

Meeps (10kg) and Moops (8kg) are having a tug of war contest. Both of them are pulling as hard as they can but neither one is moving. How much work has Meeps done if she applied a force of 25N?

Answer 1

0 joules

Explanation:

Work done is defined as dot product of force and displacement.

Let $w$ denote work done.

Let $F$ denote force.

Let $S$ denote displacement.

So,$W=F.S$

It is given that $F=25N$

It is given that both of them are not moving.

So,$|s|=0$

Since $W=F.S=|F||S|cos(\text{angle between F and S})$

So,$W=0$
