4) Two small particles of masses 6 kg and 3 kg are attached to the ends of a light inextensible string. The string passes over a smooth pulley at a height of 5 m above the ground.
The system is released from rest with both particles hanging vertically at a height of \( 2 m \) above the ground. The 6 kg hits the floor. Will the 3 kg particle reach the pulley in the subsequent motion?
