since the large wheel has a large radius as compared to small wheel. SO, everytime the large wheel turns once, the small wheel turns through several times. this is what we call angular velocity. so the angular velocity of small wheel is greater than the large wheel

Consider an old-fashioned bicycle with a small wheel of radius 0.12 m and a large wheel of radius 0.8 m. Suppose the rider starts at rest, accelerates with a constant acceleration for 1 minutes to a velocity of magnitude 15.6 m/s. He maintains his velocity for 10.9 minutes and then decelerates, with constant deceleration, for 4.1 minutes. Find the total angle through which a point on the small wheel has turned.
