Sarah throws a ball to Julie. The ball leaves Sarah's hand a distance 1.5 meters above the ground. It is moving with a speed of 15 m/s when it reaches a maximum height of 6 m above the ground.
What is the speed of the ball when it leaves Sarah's hand?
How high above the ground will the ball be when it gets to Julie? (note, the ball may go over Julie's head.)
