Question 62

In this question, use $\text{ m s}^{-2}$ .

A robotic transport sled, $S$ , is pulled across a rough horizontal factory floor.

A horizontal pulling force of magnitude $P$ newtons acts on $S$ .

$S$ moves with a constant acceleration of $\text{ m s}^{-2}$ .

$S$ has a weight of $\text{ N}$ .

The only resistance force acting on $S$ is due to friction.

The coefficient of friction between $S$ and the floor is $0.3$ .

Find $P$ .
