When a body slides down from rest along a smooth inclined plane making an angle of $45^?$ with the horizontal, it takes time $T$. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time $pT$, where $p$ is some number greater than $1$. The co-efficient of friction between the body and the rough plane is
