Inspired by Roddick155mph's poll, does throwing distance vary directly with serving speed?
Here's my take on this:
Assuming the angle of the throw is constant, a person who throws a tennis ball with a faster speed would result in the ball flying farther. Just like in the formula d=rt, the distance would increase when the rate would increase assuming the time stays the same. So a person throwing a ball with a faster arm acceleration would make the ball fly farther. This can relate to serving speed. The speed is determined by the force generated by the player can the power transfering to the racket. Well F=ma according to Newton's second law of motion, the force would increase as acceleration increases, that is when the mass is constant (which should be the case since the mass doesn't change before the person serves and during when the person serves). So if the person swings his arm faster in an attempt to make the ball fly faster, that would mean an increase in speed. The resulting serve would fly faster. So I would say throwing distance and serving speed vary directly.
