You need to have a quick reaction time to survive as a tennis player. You have less than a second to prepare for a serve. To be precise, you have 0.6 seconds.
If you were a baseball player, you would have to be even quicker. You need a reaction time of 0.4 seconds to hit a fastball.
Luckily, the laws of physics are working with you to slow down the tennis ball. By the time the tennis ball reaches you it is traveling at half the speed it started out at. A serve that starts out at 100 miles per hour, would be traveling 50 mph by the time it reaches you.
The fuzz on the ball slows it down as it flies through the air. The impact on the ground also slows down the ball.
