A skateboarder is approaching a set of stairs at a speed of 8 m/s. The stairs drop a vertical distance of h=3 meters and take up a horizontal distance d=5 meters. As the skater reaches the edge she can give herself a vertical component of velocity by jumping. Note: this does not change her horizontal velocity.

Question

A skateboarder is approaching a set of stairs at a speed of 8 m/s.  The stairs drop a vertical distance of h=3 meters and take up a horizontal distance d=5 meters.  As the skater reaches the edge she can give herself a vertical component of velocity by jumping.  Note:  this does not change her horizontal velocity. 
a.) What vertical velocity should the skater have in order to clear the stairs?
b.) Repeat with V=7m/s, 6 m/s, 5m/s, 4m/s

I don't understand why somebody changes names each time they post a new problem (without work). I will be happy to critique your work.
