A flywheel is a solid, rotating disk that is sometimes used to store energy. The moment of inertia for a solid disk is 1/2MR^2 where M is the mass and R is the radius. If a flywheel weighs 15kg and has a radius of 0.8m, determine the following. A) If a point on the outside of the disk is moving at 6 m/s, what is the angular velocity of the flywheel? B) If the flywheel starts from rest...
