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 is incredibly wrong, so I want to find a reputable source that says it is wrong. ( I was using bad equipment, thats why my results were so messed up). So if anyone can find an article that actually gives a terminal velocity of a tennis ball numerically that would be awesome!!! Thanks in advance.
