When a person pedals a bicycle, the front sprocket moves a chain that drives the back wheel and propels the bicycle forward. For each rotation of the front sprocket the chain moves a distance equal to the circumference of the front sprocket. The back sprocket is smaller, so it will simultaneously move through a greater rotation. Furthermore, since the back sprocket is rigidly connected to the back wheel, each rotation of the back sprocket generates a rotation of the wheel. Suppose that the front sprocket of a bicycle has a 4 -in . radius and the back sprocket has a 2 -in . radius. a. How much chain will move with one rotation of the pedals (front sprocket)? b. How many times will the back sprocket turn with one rotation of the pedals? c. How many times will the wheels turn with one rotation of the pedals? d. If the wheels are 27 in . in diameter, how far will the bicycle travel with one rotation of the pedals? e. If the bicyclist pedals 80 rpm , what is the linear speed (in ft/min) of the bicycle? f. If the bicyclist pedals 80 rpm , what is the linear speed (in mph) of the bicycle?
