Pre-lab (to be completed and submitted via Sakai before class): A round object with a rotational inertia of I = BM(R^2), where B is a constant, M is its mass and R is its radius, rolls without slipping a distance "d" down a plane inclined at an angle "Theta". a) If it started from rest, what is its speed? b) What percentage of its total kinetic energy is rotational?
