Question

Consider the system shown in the figure. Here, the pulleys can move in a vertical plane, points A and B are on the rope, point C is the centre of the indicated moving pulley while point D is a point on the rope near the bottom of the middle pulley. The strings are taut.

List - I	List - II
(I) Speed of point A must be	(P) $5 m / s$
(II) Speed of point B must be	(Q) $1.5 m / s$
(III) Speed of point C must be	(R) $3 m / s$
(IV) Speed of point D must be	(S) $17 m / s$
