What Is the Initial Speed of a Diver Jumping from a 10m Board?

[Matt1234]

Homework Statement

A diver jumps from a 10 m high diving board at an angle of 30 deg above horizontal. 2 seconds later the diver reaches water. What is the initial speed of the diver ?

Homework Equations

v = vi + at
s = si + vit +0.5(a)t^2
v^2= Vi^2 + 2 a (s-s0)

The Attempt at a Solution

I tried applying the above equations yet i can't seem to come up with the method. I know Acceleration is constant 9.81 m/s^2. But the initial velocity is throwing me off, i have also tried to break the velocity into components, but was unseccessful.
Thank you.

Show what you've tried. Hint: If the initial velocity is 'v', what's the vertical component?
