Here’s some good golf mumbo jumbo for those of you who are so into golf. Not that I am not, but this really takes the “grip and rip it” out of your game.
My advice? GO hit the ball first… All this you can think about after you start shooting near par… This article must have been written by a Physics Professor who couldn’t break 90…

There is a relationship between the speed of the club head and the initial velocity of the ball. This relationship depends on the coefficient of restitution of the ball, which varies between different types of balls. When the ball is struck by the club, it is deformed and flattened by the force of impact (balls with harder cores deform less than softer balls). In general, a harder ball will travel further than a softer ball because it deforms less and will efficiently transfer more energy from club to ball. During the impact between the ball and club head, kinetic energy is transferred and stored as the ball tries to regain its original shape. This coefficient of restitution is quite similar to the restoring force we discussed in class. To obtain maximum distance in the drive, a ball must be selected that maximizes restitution for the club speed. If the chosen ball is too soft for the club speed, too much energy will be spent deforming the ball and not enough energy will be stored in the ball. Similarly, if the ball is too hard for the club speed, then the ball will not deform enough, and again, will not transfer adequate energy. This is why it is important to choose a ball that matches the club speed. Here is a graph relating initial velocity of the ball with club speed:
