Answer:
Average force, F = 562.5 N
Explanation:
Mass of the golf ball, m = 0.045 kg
Initially, it is at rest, u = 0
Final speed of the ball, v = 25 m/s
The club and the ball are in contact for, ![t=2\ ms=2\times 10^{-3}\ s](https://tex.z-dn.net/?f=t%3D2%5C%20ms%3D2%5Ctimes%2010%5E%7B-3%7D%5C%20s)
We need to find the average force acting on the ball. It can be calculated using the formula as :
![F\times t=m(v-u)](https://tex.z-dn.net/?f=F%5Ctimes%20t%3Dm%28v-u%29)
![F=m\dfrac{v-u}{t}](https://tex.z-dn.net/?f=F%3Dm%5Cdfrac%7Bv-u%7D%7Bt%7D)
F = 562.5 N
So, the average force acting on the ball is 562.5 N. Hence, this is the required solution.
