Problem 2-43 - Free fall (b)

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!

After the ball leaves the pitcher's hand it is subject to the constant acceleration of \(\mathrm{9.8\; m/s^2.}\)

During its flight first up and then down:

(A)  It is accelerated up in the upward path and down in the downward path.

(B)  It is accelerated down in the upward path and up in the downward path.

(C)  It is accelerated down in its upward and downward paths.
