A student standing on the ground throws a ball straight upward. the ball leaves the student's hand with the speed of 9.0 m/s when their hand is 1.8m above the ground. the ball travels upward then comes back down and hits the ground (the student moves their hand out of the way) show all steps of the work including starting equations.

1. draw a diagram of the situation, include all relevant variables and a coordinate system.
2. determine the maximum height the ball reaches while in the air
3. determine the speed of the ball immediately before it hits the ground
