A) The 4 kg disk shown in Figure Q1 is initially at rest. A force of F = 50 N is applied to the thin, inextensible cable wrapped round the disk diameter d = 156 mm. Calculate the work done on the disk after it has turned through 8.8 revolutions. [Answer in J] 30 Q1 b) Assuming that the 8 kg disk in Question 2 is initially at rest and a force of F = 67 N is applied to the thin, inextensible cable wrapped round the disk diameter d = 177 mm. Find the angular velocity of the disk after it has turned through 8.1 revolutions. [Answer in rad / s]
