What kind of chest protector...

(Clarification: A ball thrown at 70 mph from 250' will slow down more than a ball thrown at 70 mph from 46'. So, by the time the ball hits the target, it will be moving slower and impart less force. Someone else can do the math. The difference between 46' and 60' is not going to be significant from a practical matter in this case.)

Some folks can fire a cannon that appears to float though the air for longer periods of time than others thrown at the very same speed. Gravity and spin can't explain it all, but drag and lift can.

Now assuming both balls will come to a stop, some folks will say the two balls slow down the same amount, 70mph to 0 mph. But I know what you mean about their deceleration.

In related news, Reds prospect clocked at 105 mph.
