A round object has a rotational inertia of I = ?MR2, where ? is a constant, M is its mass and R is its radius. It rolls a distance d down a plane inclined at an angle ?, without slipping.
Part A: If it starts from rest, what is its speed v at the distance d? Express the answer in terms of the given variables and any other constants necessary.
Part B: What fraction of the total kinetic energy is rotational? Express your answer in terms of ?
