A golf ball with m = 46 g is struck a blow which makes an angle of 45o with the horizontal. The drive lands 200 m away on a flat fairway. If the golf club and ball are in contact for a time of 7 ms, what is the average force of impact?

Average force will be equal to 2908.57 N  

Explanation:

We have given mass of the ball m = 46 gram = 0.046 kg

Let velocity at which ball is projected is u m/sec

Angle at which ball is projected

Range of the ball is given R = 200 m

Range is equal to

u = 44.27 m/sec

Change in momentum of the ball is equal to

Time of impact is given

Force is equal to rate of change of momentum

So force

Force will be equal to 2908.57 N
