During a drive by golfer Brooke Henderson, the angular velocity of her club is zero at the top of the backswing and 1620 deg/s at the bottom of the downswing just before impact with the ball.

b) If the downswing lasts 0.32 s, what is the average angular acceleration of the club during the downswing in deg/s²?

B) What is the average angular acceleration of the club during the same downswing in rad/s²?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
