Problem 10CQ
A golfer starts with the club over her head and swings it to reach maximum speed as it contacts the ball. Halfway through her swing, when the golf club is parallel to the ground, does the acceleration vector of the club head point (a) straight down, (b) parallel to the ground, approximately toward the golfer’s shoulders, (c) approximately toward the golfer’s feet, or (d) toward a point above the golfer’s head? Explain.
ANSWER:
Step 1 of 2
The golfer starts swinging her club over her head and swings it to hit the ball. Assume that halfway through her downswing, the club is parallel to the ground, the centripetal acceleration that rotates the golfer points in the direction of the player, tangential acceleration points in the direction of the ground and the resultant vector points approximately toward the feet of the golfer.
