A small rubber wheel is used to drive a large pottery wheel. The two wheels are mounted so that their circular edges touch. Thesmall wheel has a radius of 2.0 cm and accelerates at the rate of7.4 rad/s2, and it is incontact with the pottery wheel (radius 25.0 cm) without slipping.
a) Calculate the angular acceleration of th epottery wheel.
b) Calculate the time it takes the pottery wheel to reach its required speed of 58 rpm.
