A small rubber wheel (radius of 2.60 cm) is used to drive a large pottery wheel (radius of 33.00 cm), and they are mounted so that their circular edges touch. If the small wheel accelerates at the rate of 7.10 rad/s2, and there is no slipping, what is the angular acceleration of the large pottery wheel?
Then the second part of the equation says
In the above problem, what is the time taken for the pottery wheel to reach the required speed of 72 rpm?
- W0 would cancle leaving the formula
72RPM = 7.54 rad/s
7.54/.6 = 12.5667 s
This seems right but it keeps telling me im wrong
