Q2. Two masses initially at rest are connected by a cable which passes over a tight frictionless pulley as shown in Fig Q2. Mass A is 45 kg and mass B is 65 kg. The coefficient of friction for mass A is 0.27 and the coefficient of friction for mass B is 0.23. The system is then released.

 Calculate EACH of the following:

(a) The common acceleration of the masses; (10)

(b) The time taken for mass A to reach a velocity of 1.5 m/s; (3)

(c) The displacement of mass B after 2.5 seconds. (3)
