angular acceleration?

a potter's wheel moves from rest to an angular speed of 0.20 rev/s in 30.0 s. Assuming constant angular acceleration, what is its angular acceleration in rad/s^2?

angular acceleration = change in angular speed / time over which change occurs

so 0.20 rev/s divided by 30.0 s is the answer in rad/s^2

w = @ X T where T= time, @ = angular acceleration and w = final angular velocity
