1. The problem statement, all variables and given/known data Problem: A solid cylinder of mass 3.0 kg and radius 0.2 m starts from rest at the top of a ramp, inclined 15 degrees, and rolls to the bottom without slipping. (I = 0.5MR^2). The upper end of the ramp is 1.2 m higher than the lower end. Find the lindear speed of the cylinder when it reaches the bottom of the ramp. 2. Relevant equations Equations: I = 0.5MR^2 = 0.6 3. The attempt at a solution Do I use angular momentum here? Really have no idea. Thanks.
