Michael Jordan makes a throw from the outfield to home plate in an attempt to throw out the runner on a sacrifice fly. He throws the ball at 45 m/s and the ball is caught by the catcher on the fly at approximately the same height as the height at which the ball left Jordan's hand.
The ball undergoes a horizontal displacement of 100 m in a time of 2.3 s
a) At what angle did Jordan release the ball?
b) What is the maximum height (above the release height) of the ball during its flight?
