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 2.9cm and accelerates at the rate of 7.9rad/s^2 , and it is in contact with the pottery wheel (radius 24.0cm ) without slipping. Calculate the angular acceleration of the pottery wheel. Calculate the time it takes the pottery wheel to reach its required speed of 68rpm.
