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

Respuesta :

Answer:

Average force exerted by club on the ball is 3375 N

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 [tex]P=mv=0.045\times 75=3.375kgm/sec[/tex]

We have to find the average force

Force is equal to rate of change of momentum

So force [tex]F=\frac{dP}{dt}=\frac{3.375}{0.001}=3375N[/tex]

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