Now, since we have our distance and our time, we can use the equation to find the answer. The equation to find how fast you throw a baseball without using a radar gun is: Distance / Time = Speed Now since we are trying to calculate how fast we throw a baseball, we usually use mph.sing the formula above D/T=S .0106 / .000116 = 91.379 mph So, to calculate how fast you throw a baseball in mph without using a radar gun, this is the formula you should use.
Exit speed is generally faster than bat speed. A 20% variance would be a very rough rule of thumb. The formula is exit speed=q*(pitch speed) + (1+q)*(bat speed) where q is roughly 0.2 for a wood bat. Average MLB fastball speed is 91 mph out of the hand, and 83 mph at the plate. Example: MLB average exit speed is 103 mph, bat speed ranges roughly from 70-85 mph. Wood bats generate a lower exit speed than a non-wood bat.
