1. Nathan performs a triple twisting jump while figure skating. He rotates around his longitudinal axis three times while he is in the air. The time it takes to complete the jump from takeoff to landing is 0.68 s. Find Nathan's average angular speed in: a. radians (5 points) b. revolutions (5 points) c. degrees (5 points) 2. Nelly is approaching the golf tee. The angular velocity of her club is zero at the top of the backswing and 25 rad/s at the bottom of the downswing just before she impacts the ball. The downswing lasts 0.25 s, and the distance from the club head to the axis of rotation is 1.8 m. a. What is the average angular acceleration of the club during the downswing? (10 points) b. What is the linear velocity of the club head just before impact with the ball? (10 points)
