A 0.0450-kg golf ball initially at rest is given a speed of when a club strikes. If the club and ball are in contact for 2.00 ms, what average force acts on the 25.0 m>s 55 m>s, 73.14 m>s. 2.60 m>s. 2.75 m>s +y-direction) at 23.0 m>s. 14.0 m>s K = p2 >2m. 15.0 m>s 12.0 m>s? Exercises 269 ball? Is the effect of the ball’s weight during the time of contact significant? Why or why not?
