Question

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?

Answer 1

v = 176 mph = 78.68 m/s

mavnitude of impulse

I = mv = 45.9* 10^-3* 78.68

I = 3.611 kgm/s
