11.) A disk, a solid sphere, and a ring, all with radius 0.4 m and with masses of 2 kg, roll along
the path shown in the figure below. They all are initially rolling such that their center of mass velocities
are all equal to 3 m/s. Rank in order, from smallest to greatest, the heights that these shapes achieve on
the incline. (Assume friction is present to roll appropriately, but negligible enough to exclude otherwise.
They all start at the same position but are separated in the picture to demonstrate the differences in shape.)
