Physics question? Someone help?

A diver steps of the platform 10m above a swimming pool. Determine the
(i) acceleration during fall
(ii) velocity of the diver at the instant she steps of the platform
(iii) velocity of the diver at the instant she hits the water
(iv) time that the diver is in the air
(v) average velocity of the diver during fall

v2=u2+2as

After the second question I'm lost. I know the acceleration is 9.81 m/s 2 sure to gravity and the velocity is 0 m/s because she hasn't left the board yet.
