116* Write down the Lagrangian for a cylinder (mass m, radius R, and moment of inertia l\" ) that rolls without slipping straight down an inclined plane which is at an angle or from the horizontal. Use as your generalized coordinate the cylinder's distance a: measured down the plane from its starting point. Write down the Lagrange equation and solve it for the cylinder's acceleration it\". Remember that T = z'mv2 + g! 1:92, where U is the velocity of the center of mass and a:- ie the angular velocity
