Three equal point masses are connected by very light, rigid rods in an L shape. Rotation around which axis perpendicular to the page results in the smallest moment of inertia? The axis of rotation in each choice is indicated by O. A B C A solid uniform sphere rolls without slipping along a horizontal surface with transla- tional speed v, comes to a ramp, and rolls without slipping up the ramp to height h, as shown. Assuming no losses to friction, heat, or air resistance, what is h in terms of v? The moment of inertia of a rolling solid sphere is Iem = MR. Assume acceleration due to gravity is g = 9.8 m/s.
