It would be the same speed as it would be on a very still day on earth without any wind. Wind creates resistance which sends the ball in different directions on serves and returns. On the moon, since there is no atmosphere there is no wind and the ball would go where ever you hit it without any effect from resistance. So trying to get a good serve in will be hard since the ball won't be as tricky to hit back.

What is the difference between terminal speed and terminal velocity?
The difference between terminal speed and terminal velocity is really simple. Terminal speed can be used to refer to the maximum speed an object can reach before factors like friction prevent anymore speed to be gained. Terminal velocity, however, generally refers to the rate at which this speed was gained.
What is the reason for rain drops to fall with a constant speed by the time they reach earth?
They reach their terminal velocity.
Why a helicopter falling during auto-rotation could reach a terminal speed without the pilot changing any controls?
The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating. Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.
Why can a helicopter reach a terminal speed whilst falling during autorotation?

How can you measure when an object has reached terminal velocity?
the terminal velocity is the total speed that its take an object to reach the point it required from the initial velocity
When you skydive Why don't you hit maximum speed before you hit the ground?
The maximum speed you can reach is also known as terminal velocity and this is the speed at which your mass is resisted by the air. Typically in a belly to earth body position, this is around 120mph. It takes around 10 seconds to reach this speed. The minimum exit height is 2500ft and would not reach this terminal velocity before they need to deploy their parachute. Most skydivers jump from a lot higher - between 10,000ft and 15,000ft. This gives them a freefall time of over 45 seconds and therefore they reach terminal velocity. Once the parachute is open, the decent rate is less than 10mph, so no you do not hit the ground at maximum speed in answer to your question.
When a airplane is traveling forward at 120 miles per hour and a bowling ball is dropped from the plane which way would the ball travel?
It would move slightly backwards due to no air resistance------------------------------------------------------- The above answer is rubbish. It would continue travelling forward. Whilst travelling forward it would also travel down. It would continue to travel forward until it slowed down to a zero forward speed ( DUE to air resistance ) but a terminal downward speed. Whether or not it would reach a zero forward speed and terminal downward speed would depend on how high it was when it was dropped.
When a object falls what does it reach because of air resistance?
When an object falls, air resistance causes it to reach a terminal velocity. After that, it does not increase the speed of falling, no matter how far it has still to fall.
Is it true that the steady speed reached by a skydiver is called the terminal velocity?
Yes. Not just a skydiver; anything that falls long enough will eventually reach "terminal velocity", which means that it will continue falling at a constant speed, because the force of gravity and the force of air resistance are in balance.
When a person skydives from very high distance does the speed in which they are falling continue to increase the entire way down?
After about 10 seconds you reach terminal velocity your speed remains constant till the parachute opens.
How does a skydiver reach terminal speed?
When he first jumps, his weight is the only force acting on his body. As he accelerates, the air resistance force, which acts in the opposition direction to the weight, increases in magnitude. When these two forces equal, they cancel each other out, which means that the diver does not accelerate anymore. This speed is the terminal speed. It's all a matter of forces.
What speed would a car from 1900 reach?
About 60,000 miles
