# 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?

Correct!

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

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
