A thin rod of length 0.75 m and mass 0.40 kg is suspended freely from one end. It is pulled to one side and then allowed to swing like a pendulum, passing through its lowest position with angular speed 4.5 rad/s. Neglect friction and air resistance. (a) Find the rod's kinetic energy at its lowest position. J (b) Find how far above that position the center of mass rises. m
