If a 75-kg skater starts his skate at 8.0m, at his lowest point (height = 0), what is his velocity?

Is this some kind of downhill skating?
Are you supposed to ignore friction?
Is he starting the skate with zero velocity?
This is a pretty far-fetched question. I suppose they want you to use conservation of energy.
That will result in V(final) = sqrt(2gH)
where H = 8 m.
The weight won't make a difference.
