A bicycle has wheels of radius 0.33 m . Each wheel has a rotational inertia of 0.081 kgm^2 about its axle . The total mass of the bicycle including the wheels and the rider is 71 kg . When coasting at constant speed , what fraction of the total kinetic energy of the bicycle (including rider) is the rotational kinetic energy of the wheels ?
