Academics

A softball pitcher throws a ball straight upward as hard as she can. According to your stopwatch, it takes exactly 4.20 seconds for the ball to fall back to the pitcher's hand. Assuming no air drag:

(A) What was the speed at which the pitcher threw the ball upward?

(B) What is the maximum height reached by the ball?

(C) It takes 2.10 seconds to reach maximum height. At half of that time, 1.05 seconds, how high is the ball? (Is it half-way to maximum height?)
