A baseball pitcher throws a baseball ?

A baseball pitcher throws a baseball (145 grams) towards the batter at a speed of 35 m/s. The batter swings her bat (940 grams) with an unknown speed towards the ball. The bat hits the ball, and the ball goes flying back toward the pitcher at a higher speed. If the ball’s speed (not velocity) increases by about 20% and the bat’s speed decreases by about 50%, what was the initial speed of the bat before it hit the ball?
