Problem 1 An amusement park ride consists of a car which is attached to the cable OA. The car rotates in a horizontal circular path and is brought to a speed 1/4 ft/s when r=12 ft. The cable is then pulled in at the constant rate of 0.5 ft/s. Determine the speed of the car in 3 s. Problem 2: The drum shown weighs 80lb and has a mass moment of inertia about 0 of 0.8 Ib.ft?. Starting from rest, the cable wrapped around the drum is subjected to a vertical force P which resulted in a constant angular acceleration of 20 rad/s. Determine magnitude of P and the reaction at the support pin at O. Neglect the mass of the cable 0311
