Sarah throws a ball to her friend Julie. What is the speed of the ball...?

Sarah throws a ball to her friend Julie. However, Sarah throws it too hard so it is over Julie's head when it reaches Julie's horizontal position. Assume the ball leaves Sarah's hand a distance 1.5 meters above the ground, reaches a maximum height of 8 m above the ground, and takes 1.44 s to get directly over Julie's head.

1) What is the speed of the ball when it leaves Sarah's hand?

2) How high above the ground will the ball be when it gets to Julie?
