Rotational Kinetic Energy: Work and Energy Revisited (Problem 32)

What is the moment of inertia of an object that rolls without slipping down a 2.00-m-high incline starting from rest, and has a final velocity of 6.00 m/s? Express the moment of inertia as a multiple of ${\text{MR}}^2$, where $M$ is the mass of the object and $R$ is its radius.
