**bobpursley**, Saturday, December 4, 2010 at 9:47pmInitial total energy-friction force=final energy.

Let the final energy be KE only, set PE to zero, after all, that point is arbritary.

1/2 m 1.8^2+mgh-frictionwork=1/2 m 6^2

solve for h

1/2 m 1.8^2-265=1/2 m*26

solve for h. If h is negative, then the skater is above the starting point.
