A hollow spherical ball of radius 0.19 m and mass 0.12 kg rolls without slipping down a half-pipe. Starting from rest at a height $h = 8.5$ m above the lowest point in the half-pipe, and ignoring all non-conservative forces, how high up the other side of the half-pipe, in meters, will the ball reach? Enter only the numerical value, no units. Enter the answer as X.X, round to the nearest decimal place.
