A major League pitcher stands on top of a 100m cliff. He throws a baseball straight upwards with a speed of 30.5 m/s. ignore air friction, ignore the height of the pitcher.

Q: What is the maximum height above the ground the ball rises to?
Q: What is the path length of the ball for the entire trip from hand?
Q: What is the average velocity of the ball for the entire trip from hand to the ground below just before hitting the ground?

pls show me how to work this out.
