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

  • Physics - ,

    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.
