A uniform cylinder of mass m=6.30 kg and radius R=0.132 m is released from rest on an inclined plane (theta=32.7 deg) and rolls without slipping onto a horizontal surface. The center of mass falls h=0.798 m in the process. What is the speed of the center of mass of the cylinder just before it reaches the horizontal surface?
