A uniform solid cylinder of mass 2.0kg and radius 0.10m is released from rest at the top of a frictional ramp that is 1.5m lower than the bottom of the ramp. Throughout the motion the cylinder rolls without slipping and air resistance is negligible.
(a) Calculate the speed of the cylinder’s center of mass when it reaches the bottom of the ramp.
(b) Determine the fraction of the cylinder’s total kinetic energy at the bottom that is translational.
