Question: A diver springs upward from a diving board. At the instant she contacts the water, her speed is 8.90 m/s, and her body is extended

A diver springs upward from a diving board. At the instant she contacts the water, her speed is 8.90 m/s, and her body is extended at an angle of 75.0° with respect to the horizontal surface of the water. At this instant her vertical displacement is -3.00 m, where downward is the negative direction. Determine her initial velocity, both magnitude and direction?
