During a drive by golfer Ai Miyazato, the angular velocity of her club is zero at the top of the backswing and 30 rad/s at the bottom of the downswing just before impact with the ball. If the downswing lasts 0.30 s, what is the average angular acceleration of the club during the downswing?

Answer: The angular acceleration =

100rads/s^2

Explanation:

Angular acceleration is defined as the angular velocity dividing by the acceleration time.

Given:

Angular velocity of ball = 30rads/s

Acceleration time of the ball = 0.30seconds

Angular acceleration = (30rads/s) / (0.3 secs)

Angular acceleration = 100rads/s
