Question

In a typical golf swing, the club is in contact with the ball for about 0.0010 s. If the 45 g ball acquires a speed of 75 m/s, estimate the magnitude of the force exerted by the club on the ball. N

Answer 1

Average force exerted by club on the ball is 3375 N

Step-by-step explanation:

We have given mass of the ball m = 45 gram = 0.045 kg

Speed acquires by the ball v = 75 m/sec

It is given that ball is in contact with club for 0.001 sec

Momentum of the ball
`P=mv=0.045* 75=3.375kgm/sec`

We have to find the average force

Force is equal to rate of change of momentum

So force
`F=(dP)/(dt)=(3.375)/(0.001)=3375N`

So average force exerted by club on the ball is 3375 N
