Problem: A diver springs upward from a diving board. At the instant she contacts the water, her speed is 9.30 m/s, and her body is extended at an angle of 72.0° 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.
Part A: Determine her initial velocity, both magnitude and direction.
