A diver springs upward from a board that is three meters above the water. At the instant she contacts the water her speed is 9.00 m/s and her body makes an angle of 81.0° with respect to the horizontal surface of the water. Determine her initial velocity, both magnitude and direction.(adsbygoogle = window.adsbygoogle || []).push({});

magnitude m/s

direction °

Here's what I've tried to do: I tried to solve for the initial velocity by using the kinematics equation v^2=vo^2+2*a*x

vo=1.174<<initial velocity

Now I need to find the magnitude and the direction, I think you use tan-1 and pythagorean theorem but I don't really understand the component method very well. Could you please help me get on the right track for this problem. All help will greatly be appreciated.
