A professional golfer is examining a video of a practice swing. The high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Δ?=0.571, and the radar gun clocks the speed of the ball as ?b=131 after it comes off the club. The golf ball has a mass of ?b=45.9. What is the magnitude of the impulse imparted to the ball by the club? What is the magnitude of the average force of contact between the club and the ball?
