Question

If Rohan does a work of $600J$ by moving a cart for $20m$. How much force would he have applied to do so?

Answer 1

We know that work done = Force$\times$ Displacement in the direction of force.
When no direction is mentioned, assume that the displacement is in the direction of force.
Given,
Work done = $600J$
Displacement = $20m$
Work done = Force $\times$ Displacement in the direction of force
$600$ = Force $\times 20$
Force = $30N$
