Generic intuition pump: take much more extreme values: what happens if the ball is thrown at a million miles per hour? Maybe it bounces back at a million miles per hour, maybe the batter looks in dismay at the pile of splinters that used to be his bat ... so it depends of what your model of the batter is. The question as asked doesn't allow to answer that question, though you could probably estimate a reasonable model of a batter.
There's probably a better place to ask this question, but I don't know what it is. That being said...
Which will go further if a batter manages to hit it with a baseball bat: a baseball thrown to the batter at 90 miles per hour or one thrown at 60 miles per hour?
