Two particles A and B of mass 5kg and 9kg respectively rests on the smooth faces of a fixed wedge .They are connected by a light inextensible string passing over a smooth pulley at C and are released from rest.In the subsequent motion B hits the ground and does not rebound. a.) the speed of the particles when B hits the ground. b.)the acceleration of A after B hits the ground c.) the distance of A from C when A first comes to rest.
