Rank the objects based on the maximum height they reach along the curved incline. [Solved]

With equal MASS, RADIUS and SPEED the objects would lose KE in THIS order: (ranked from least KE loss to most KE loss}:
1) solid sphere: 0.7 => (0.7)(1) = 0.7
2) solid disk or solid cylinder: 0.75 =>(0.75)(0.5) = 0.375
