Tks for your answer...

Answer
Hi Franck,

The ball speed depends on the club speed, club loft and COR (coefficient of restitution. For today's drivers, the ball speed is equal to about 1.45 times the club speed. So, the simple formula would be BS = 1.45*CS, where BS = ball speed and CS = club speed.

Hope this helps.
