Code:

`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

Code:

`In the above problem, what is the time taken for the pottery wheel to reach the required speed of 72 rpm?`

w=w

_{0}+at

- W

_{0}would cancle leaving the formula

W=at

72RPM = 7.54 rad/s

7.54/.6 = 12.5667 s

This seems right but it keeps telling me im wrong
