2) A solid cylinder of radius R is released from rest from a height / and rolls down a frictionless incline as shown. The moment of inertia of a solid cylinder is I = 1/2MR2 (M = mass of the cylinder). (a) Draw a free body diagram. What nonconservative force(s) is(are) applied to the cylinder? (b) What is the work done by that(those) nonconservative force(s)? Show ALL your work. (c) Is the total mechanical energy of the cylinder conserved? Why? Explain. (d) What is the angular speed @ of the cylinder when it reaches the horizontal surface? Use ENERGY concepts. Show ALL your work
