A3m 2m B 2m C Figure 5 Three particles A B and Chave masses 3m 2m and 2m respectively Particle C is attached to particle B Particles A and B are connected by a light inextensible string which passes over a smooth light fixed pulley The system is held at rest with the string taut and the hanging parts of the string vertical as shown in Figure 5 The system is released from rest and A moves upwards a i Show that the acceleration of 4 is 993 ii Find the tension in the string as A ascends At the instant when A is 0 7 m above its original position C separates from B and falls away In the subsequent motion A does not reach the pulley b Find the speed of A at the instant when it is 0 7 m above its original position c Find the acceleration of A at the instant after C separates from B d Find the greatest height reached by A above its original position 2 3
