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

=> 
=>
