The 30-kg reel is mounted on a 20 kg cart. The reel is free to rotate about the axle O. The radius of gyration, kO, about the mass center, O, is 250 mm and a cable is wrapped around the inner hub of the wheel. The mass of the wheels on the cart and the mass of the cable may be neglected. The system is at rest when a force, P, of 50 N is applied to the end of the cable. a) Determine the velocity of the cart after 4 seconds m/s b) determine the angular velocity of the reel, in rad/s. [Correct answers are a) 4.0 m/s b) 16 rad/s
