Homework Help: PHYSICS 2

Posted by kelsey on Monday, October 20, 2008 at 4:32am.

A 2.0 kg cylinder (radius = 0.08 m, length = 0.50 m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.77 m high and 5.0 m long.

(b) What is its rotational kinetic energy?
? J
(c) What is its translational kinetic energy?
? J

How do I find the velocity in this equation so I can use RotKE= 1/2 I w ^2 and trans =1/2mv^2
