A thin rod of length 0.75 meter and mass 0.46 kilogram 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 3.7rad/s. Ignore air resistance and friction.
(a) Evaluate the rod kinetic energy at its lowest position.
