2b) A pulley rotating in the counter clockwise direction is attached to a mass suspended from a string. The pulley's initial angular velocity is 5.40 rad/s. The mass causes the pulley's angular velocity to decrease with a constant angular acceleration a = -2.10 rad/s?. () How long does it take for the pulley to come to rest? [3 marks] (ii) Through what angle does the pulley turn during this time? [3 marks]
