A diver springs upward from a board that is three meters above the water. At the instant she contacts the water her speed is 9.10 m/s and her body makes an angle of 77.0° with respect to the horizontal surface of the water. Determine her initial velocity, both magnitude and direction.

Answer 1

The angle that her body makes with the water is not what matters here. What matters is is the angle that her center-of-mass trajectory makes with the water. Perhaps that is what they mean.
