Starting from rest at t= 0, a cyclist starts racing at constant acceleration. The wheels of the bicycle are of radius R=0.40 cm and of mass 1 kg each. The combined mass of the man and bicycle frame (without wheels) is 70 kg. When t= 10.0 s, the total kinetic energy of the cyclist and his bicycle is 4,000 J. The acceleration continues until t= 15 s, when it abruptly ceases. Through what angle does the wheel rotate in the interval t=0 to t=30 s? (Consider the wheels as hoops for the purpose of rotational inertia)
