Two persons P and Q are standing 54 m apart on a long moving belt. Person P rolls a round stone towards person Q with a speed of 9 ms¯¹ with respect to the belt. If the belt is moving with a speed of 4 ms¯¹ in the direction from P to Q, what is the speed of the stone with respect to an observer on a stationary platform?
