How fast does a golf ball travel when driven off the tee?

The United States Golf Assn. tests golf equipment to determine if it conforms to certain specifications relating to the speed with which a golf ball leaves the face of a driver. Using a standard of approximately 109 mph clubhead speed, it finds that approved golf balls leave the face of the driver at about 180 mph on the average. Greater clubhead speed (Tiger Woods, for example, can swing his driver at speeds near 120 mph) results in slightly higher ball speed and longer drives.
