A golf ball (m=26.7g) is struck a blow that makes an angle of 33.6 degrees with the horizontal. The drive lands 190m away on a flat fairway. The acceleration of gravity is 9.8 m/s^2 . If the golf club and ball are in contact for 7.13 ms, what is the average force of impact?

Th average force impact is

Explanation:

From the question we are told that  

   The mass of the golf ball is  

    The angle made is

    The range of the golf ball  is

     The duration of contact is

Generally the range of the golf ball is mathematically represented as

Here v  is the velocity with which the golf club propelled it with, making  v the subject

=>    

=>    

Generally the change in momentum of the golf ball is mathematically represented as

here u  is the initial  velocity of the ball before being stroked and the value is 0 m/s

=>    

Generally the  average force of impact is mathematically represented as      

=>        

=>        

i already answered it by 34/s

conservation of mass

mass before something happens = mass afterwards
