When a pitcher throws a baseball, it reaches a top speed of 39 m/s. If the baseball takes 1.5 seconds to travel from the pitcher to the catcher, what is its acceleration? (Assume the ball is moving at 0 m/s right before it leaves the pitcher's hand.)
O A. 26 m/s2
OB. 23 m/s²
O C. 11 m/s²
OD. 17 m/s²
