When a turntable rotating at 33 1/3 rev/min is shut off, it comes to rest in 26 s. Assume constant angular acceleration. (a) Find the angular acceleration. rad/s2 (b) Find the average angular velocity of the turntable. rad/s (c) Find the number of revolutions it makes before stopping. rev For Part A I did: omega = omega initial + alpha * t omega = alpha * t omega/t = alpha (33.3 rev/min) / (26s) * (2Pi rad) / (1 rev) * (1 min) /(60s) = .1341218402 rad/s^2 = approx .13 rad/s^2 but this is wrong. For Part C: displacement = omega initial + 1/2 alpha * t^2 = 1/2(.1341218402 rad/s^2)(26s)^2 =45.33318199 approx = 45 revolutions. For Part B is it taking the average of initial omega velocity and final omega velocity?
