Tilden holds the title of World's fastest tennis ball served among men with a speed of 73.14 m/s (163.6 mph). So where does the fastest tennis serve rank among other sports? It is ranked third, trailing behind badminton with a fastest recorded smash of 89 m/s (199 mph) and jai-alai, where a pelota was thrown at 84 m/s (188 mph) in 1979.
Velocity is the speed of something in a given direction. The velocity of the serve is created by how fast the racket is able to accelerate to the ball, and how energy is transferred to the ball. As your racket comes in contact with the ball, having a forceful internal rotation of your shoulder helps create a bigger racket velocity in your serve.

V = velocity of ball, variable A = 0.0012566 m^2 (area of ball) (not surface area) m = 0.0027 kg (mass of ball) When simplified this yields: a = 0.143 V^2 If Velocity = a * time, then the change in velocity (if negative) would be: V subsequent = V initial - [(0.143 * V initial 2) * time]
if the tennis ball is stationary the energy in it is its gravitational energy given by the formula MGH=E where H is height in m M is mass of tennis ball in kg and G is 9.8 meters per second...
Hitting a ball with topspin causes a Magnus force to act on the ball perpendicular to the velocity of the ball in the downward direction. Because there is an additional downward force on the ball, tennis players can hit the ball with a greater speed and have it land in the court, if they apply topspin to the ball when hitting it.
In this situation, representative values of the following are used in equation (4): V A = 65 m/s m A = 0.058 kg I B = 0.04 kg·m 2 w B = 0 rad/s e = 0.5 As shown in Case 1, the best spot to hit an oncoming ball to get the highest rebound velocity of the ball is somewhere in the middle of the racket.
A tennis ball is hit straight up with an initial velocity vo=+44m/s . At what time is the velocity of the tennis ball −22m/s? Use g=−9.8m/s2.
Therefore the vertical velocity before the ball is hit it 2.1m/s [DWN] Now that we have this information, we can use the same steps as we did to find the horizontal acceleration: Therefore the vertical acceleration is 1.9x10^3 m/s [UP]
