After careful deliberation upon this topic, I have discovered that my results are unanamous. The average speed of a tennis balls machine ranks in at a whopping 80 miles per hour.

It is hard to determine what the average speed of a tennis serve is from various players, but Sam Qurrey is among the fastest serves of all time. He has recorded a serve of 141 miles per hour at multiple events.
the top speed of a 150cc dirt bike can depend on a lot of things like if its a 2 stroke or a 4 stroke engine what kind of terrain your on and how much you way but the average is about 50-55mph
close to 600 ground MPH
The average running speed for a snake is 12 1/2 miles per hour. Snakes have to travel against the ground which inhibits their speed.
== water cooled 2 stroke about 25+ horsepower 6 speed 200 lbs these are all average through out the years average speed 65+== pretty dependable when properly maintained ==
(1,832)/(average ground speed in knots) hours.
Both tennis balls will reach the ground at the same time because acceleration due to gravity is constant for all objects regardless of their mass. The only factors that would affect their falling speed would be air resistance, but for a tennis ball and a lead-filled one, the difference in air resistance is negligible.
The speed of a piston in an engine is determined by the engine's RPM (revolutions per minute) and the stroke length of the piston. The speed can be calculated using the formula: speed = (2 * pi * RPM * stroke length) / 60. Increasing the RPM or stroke length will increase the speed of the piston.
Speed, Endurance and Strength are important for tennis.
