Answer: The magnitude of impulse imparted to the ball by the golf club is 2.2 N seconds
Explanation:
Force applied on the golf ball = ![5.0\times 10^3 N](https://tex.z-dn.net/?f=5.0%5Ctimes%2010%5E3%20N)
Mass of the ball = 0.05 kg
Velocity with which ball is accelerating = 44 m/s
Time period over which forece applied = t
![f=ma=\frac{m\times v}{t}](https://tex.z-dn.net/?f=f%3Dma%3D%5Cfrac%7Bm%5Ctimes%20v%7D%7Bt%7D)
![t=\frac{0.05 kg\times 44m/s}{5.0\times 10^3 N}=4.4\times 10^{-4} seconds](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B0.05%20kg%5Ctimes%2044m%2Fs%7D%7B5.0%5Ctimes%2010%5E3%20N%7D%3D4.4%5Ctimes%2010%5E%7B-4%7D%20seconds)

The magnitude of impulse imparted to the ball by the golf club is 2.2 N seconds
