Can someone help me with this problem: A cylindrical wooden log rolls (without slipping) down a smal ramp. Tha log has radius of 15 cm, a length of 2.0m and a mass of 85kg. What was the log's TOTAL kinetic energy at the bottom of the ramp? (Recall that Icylinder = (1/2)MR^2) . The total angular velocity i got was 200 rad/s. I don't know if the angular velocity will help solve the problem. THANKS!!
