The chain on a bicycle connects the pedal gear (with a diameter of 9 inches) and a gear centered on the same axis as the back tire. The rear gear has a diameter of 3 inches, while the tires have diameters of 28 inches. A cyclist pedals at a rate of 2.25 revolutions per second. Represent the angular velocity of the pedals in radians per second.
r=? so r/2=w
w=θ/t
w=?
anguluar velocity is
