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 At = 0.571 ms, and the radar gun clocks the speed of the ball as Ub = 161 mph after it comes off the club. The golf ball has a mass of mb = 45.9 g. What is the magnitude of the impulse imparted to the ball by the club? kg . m magnitude of the impulse: S What is the magnitude of the average force of contact between the club and the ball? N magnitude of the average force of contact
