The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 11 m/s at an angle 44 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. |dw:1441302469013:dw| ---------------------------------------------------------------- After catching the ball, Sarah throws it back to Julie.
