Johnny threw a ball upward with an initial velocity of 2000 cm /s and was able to catch it before it reached the ground on its return.
a. What is the velocity of the ball when it reaches its maximum hieght?
b. What was its final velocity just before it touched Johnny's hand?
c. What was its final velocity when Johnny catches it?

if straight up then zero at the top
2000 cm/s = 20 m/s as it hits his glove
zero if his hand stops it. 👍
