Hi there, I've been looking over the internet for a while and I am looking to find the terminal velocity of a tennis ball from a reputable source. I am writing a paper for my college classical physics class. I found the terminal velocity for a tennis ball and it was about 9 m/s. I know this...

If I have a tennis racket, and I add weight to its handle, would it make the tennis racket more maneuverable? the swing weight of the racket would not change, in fact the weight would make the racket heavier. but the weight would move the center of gravity towards my hand.

Hi, I'm writting a 3D tennis game, and I need to revamp how the computer player hits the ball. I have a simple physics model for trajectory (no air resistance) that works great, but now I need to have the computer player play smarter, and make judgements about how to get the ball over the net...

Most of the time i play table tennis and I always think about physics of table tennis . My question is . Is there any a very brief introduction to the mathematics and physics on table tennis?

1). Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory? I know that when a projectile reaches the top of its trajectory, v=0 because velocity is momentarily horizontal. However, how would I relate this to acceleration? 2). A tennis ball is hit...

OK. I have been fighting with my pen and paper for hours trying to fathom this: I have been thinking about that childs game where there is a post, and two players. On the post is a string with a tennis ball attached at the top, each player has a tennis raquet and they hit the ball around the...
