halosh92:
two particles P and Q of masses 3kg and 6kg respectively are attached to the ends of a light inextensible string.
the string passes over a smooth fixed pulley . the system is released from rest with both masses a distance of 2m
above a horizontal floor. find how long it takes for particle Q to hit the floor.
assuming particle P does not reach the pulley find its greatest height above the floor
i got the time which is 1.11 but i cant get the distance.
