Problem 2-43 - Free fall - Part 3 (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?

Partially correct!

But we also know the displacement.

 The displacement is:
 
(A)  \(\mathrm{2\times \;the \;distance\; the\; ball \;rises}\)

(B)  \(\mathrm{9.8\; m}\)

(C)  \(\mathrm{0}\)
