They can pedal faster or they can have a bigger wheel. Even for sporty people, about 100 turns a minute is the limit to how fast they can turn the pedals. A typical bicycle might have a wheel of 0.7 m, but the penny-farthing often had a front wheel of 1.5 metres (about 1.6 yards). 1 turn of the pedals moves the bicycle 3.142 x 1.5 metres forward, i.e. 4.7 metres.
Homework â Circular Motion. 1. A 0.013 kg rubber stopper is attached to a 0.93 m length of string. The stopper is swung in. a horizontal circle, making one revolution in 1.18 seconds. Find the speed of the stopper, the centripetal acceleration of the stopper, and the force the string exerts on the stopper. 1.18sec 2 2 (0.93m) T r v S S = 4.95 m/s m m s r v a c 0.93 (4.95 / )2 = 26.35 m/s 2 (0.013 )(26.35 / 2) 2 ma kg m s r mv F c =0.34 N 2. Suppose the mass of the rubber stopper above is doubled, but all other given quantities remain the same. How would the velocity, acceleration, and force change?
