If the rider presses on the pedal with a force P160 N as shown, determine the resulting forward acceleration of the bicycle. Neglect the effects of the mass of rotating

parts, and assume no slippage at the rear wheel. The radii of sprockets A and Bare 45 mm and 90 mm, respectively. The mass of the bicycle is 13 kg and that of the rider is 65 kg.Treat the rider as a particle moving with the bicycle frame, and neglect drive train friction.
