Problem 2-43 - Free fall - Part 4 (c)

A baseball pitcher throws a ball vertically straight upward and catches it \(4.2\; s\) later. (a) With what velocity did the ball leave the pitcher's hand? (b) What was the maximum height reached by the ball?


\(\text{Final position = Initial position, so displacement = 0}\)


What is the final velocity if the initial velocity is \(\mathrm{v_{0_y}}\)? (We choose \(+\) in the up direction.)
(A)  \(\mathrm{0}\)

(B)  \(\mathrm{v_{0_y}}\)

(C)  \(\mathrm{-v_{0_y}}\)

(D)  unknown
