Question 13

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

A small block, $P$ , is pulled across a rough horizontal plane.

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

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

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

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

The coefficient of friction between $P$ and the plane is $0.35$ .

Find $T$ .
