Problem 11: sig. gif?tid=2N74-D1-D6-44-AC90-13474 A bicyclist notes that the pedal sprocket has a radius of rp = 8.5 cm while the wheel sprocket has a radius of rw = 5.5 cm. The two sprockets are connected by a chain which rotates without slipping. The bicycle wheel has a radius R = 65 cm. When pedaling the cyclist notes that the pedal rotates at one revolution every t = 1.4 s. When pedaling, the wheel sprocket and the wheel move at the same angular speed.

Randomized Variablesrp = 8.5 cm
rw = 5.5 cm
R = 65 cm
t = 1.4 s
