A ceiling fan is rotating counterclockwise with a constant angular acceleration of 0.407 rad/s about a fixed axis perpendicular to its plane and through its center. Assume the fan starts from rest. (a) What is the angular velocity of the fan after 3.8 s? (Enter the magnitude.) 4.7 rad/s (b) What is the angular displacement of the fan after 3.8 s? (Enter the magnitude.) 13.57 X Your response differs from the correct answer by more than 10%. Double check your calculations. rad (c) How many revolutions has the fan gone through in 3.8 s? rev Need Help? Master It
