Equation for speed and velocity problems

Hey again,

So I'm having a bit of trouble finding the equation of a problem I have.

I learnt yesterday how to find position, speed, velocity and acceleration of a function, but I don't know how to find the function itself.

So the question is,

A driver jumps from a platform diving board that is 32ft above the water with initial velocity at 16ft/sec.

Then it proceeds to tell you to find speed, velocity, and acceleration.

But how do I find the function to begin with? My teacher was saying something about if it was in meter then it would be 8.5 or something like that..and it would be a -32...but I'm not sure what she was getting at so can any one please explain?

Also, the second part of the question ask when does the driver hit the water, how would I go about solving for this? Thanks again
