Two particles P and Q of masses 0.8kg and 0.6kg respectively are connected by a light inextensible string. Particle P rests on a rough horizontal table 0.7m from a smooth fixed pulley at the edge of the table. The string passes over the pulley and Q hangs freely, 0.5m above the floor. The system is release from rest. The coefficient between P and the table is 0.25. Find:
(A) the acceleration of the system
(B) the tension in the string
(C) the speed with which Q hits the floor
(D) whether P reaches the pulley
(E) the force exerted on the pulley
