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 1.8 and accelerates at the rate of 7.0 , and it is in contact with the pottery wheel (radius 30.0 ) without slipping. Calculate the angular acceleration of the pottery wheel.
angular accelelatrion big wheel= 30/1.8 *7
I am not certain of your units.
