A hula hoop with mass m (kg) and radius R (m) hangs from a peg in a garage. When someone bumps into the hoop, it swings back and forth. What is the hoop's oscillation period? (Note: the distance to the center of mass is R and the moment of inertia of a hoop about a point on its rim is I 2m R² A hula hoop with mass m (kg) and radius R (m) hangs from a peg in a garage.
