Assume that friction does not do work on the rolling object and that air resistance is negligible. Use Ei = Ef to express v2 in terms g, L, delta, and the ratio I/MR2. Suppose an object starts from rest and moves a distance L with a constant acceleration a. Recall the kinematic formula that relates its final velocity v2 to the acceleration a and L. You are home! Combine the previous two results to get a formula for the acceleration of an object that rolls without slipping down an incline. You should express a in terms of g, delta, and the ratio I/MR2.
