1 mile = 1609.344 meter
1 hour = 3600 seconds
Mass of the golf ball = mb = 45.9 g = 0.0459 kg
Initial speed of the golf ball = V1 = 0 m/s (At rest)
Speed of the ball after it comes off the club = V2 = 146 mph = 146 x (1609.344/3600) m/s = 65.27 m/s
Magnitude of the impulse on the golf ball = I
Impulse is equal to the change in momentum of the golf ball.
I = mbV2 - mbV1
I = (0.0459)(65.27) - (0.0459)(0)
I = 3 kg.m/s
Time period the club was in contact with the golf ball = t = 0.371 ms = 0.371 x 10-3 sec
Magnitude of average force of contact = F
I = Ft
3 = F(0.371x10-3)
F = 8.08 x 103 N
a) Magnitude of the impulse imparted to the golf ball by the club = 3 kg.m/s
b) Magnitude of average force of contact = 8.08 x 103 N

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?=0.371 ms, and the radar gun clocks the speed of the ball as ?b=131 mph after it comes off the club. The golf ball has a mass of ?b=45.9 g. What is the magnitude of the impulse imparted to the ball by the club? magnitude of...

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 Δt=0.571 ms, and the radar gun clocks the speed of the ball as vb=176 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?
7.16 A golf ball of mass 0.045 kg is hit off the tee at a speed of 33 m/s . The golf club was in contact with the ball for 3.90×10−3 s Find the impulse imparted to the golf ball. Find the average force exerted on the ball by the golf club.
PRACTICE IT Use the worked example above to help you solve this problem. A golf ball with mass 5.70 x 10 2 kg is struck with a club as shown in the figure above. The force on the ball varies from zero when contact is made up to some maximum value (when the ball is maximally deformed) and then back to zero when the ball leaves the club, as in the graph of force vs. time in the figure below....
