hand a distance 1.5 meters above the ground with an initial speed
of 13 m/s at an angle 52 degrees; with respect to the horizontal.

ball leaves Sarah's hand a distance 1.5 meters above the ground,
and is moving with a speed of 11 m/s when it reaches a maximum
height of 8 m above the ground. What is the speed of
the ball when it leaves Sarah's hand?
2) How high above the ground will the ball be when

head.)
