Some Points to note about club ball collision:
From 'The Physics of Golf' by T. Jorgensen
The Club head is slowed down by the collision
The Ball is sent off with a high speed at an angle above the ground with a high rate of spin
The collision is less than thousandth of a second
The club head moves less than an inch when it is in contact with the ball
Force between the ball and the club head, averaged over the time of the collision, is greater than 3000lbs
The ball is considerably flattened against the club head
Elastic properties of the ball come into play when the ball is compressed and springs away from the club head
Frictional Torque comes into play to set the ball spinning
