A resting homogenous sphere starts at a vertical height H = 45.6m above the floor at the upper end of a wavy track. It rolls without slipping until it rolls off the right end of the track. At the right end the track is horizontal and vertically at a height h = 27.6m above a point A on the horizontal floor. Determine the ball's striking distance from A.
