The small cylinder C has a mass of 10 kg and is attached to the end of a rod whose mass may be neglected. If the frame is subjected to a couple M = (8t^2 +5) Nm, where t is in seconds, and the cylinder is subjected to a force of 60 N, which is always directed as shown, determine the speed of the cylinder when t = 2 s. The cylinder has a speed v = 2 m/s when t = 0.
