A small rubber wheel is used to drive a large pottery wheel, and they are mounted so that their circular edges touch. The small wheel has a radius of 2.8and accelerates at the rate of 6.3 , and it is in contact with the pottery wheel (radius 28.0 ) without slipping.
Q1. what is the angular acceleration
Q2. Calculate the time it takes the pottery wheel to reach its required speed of 65
