Homework Help: Physics. PLEASE HELP!!

Posted by Amber on Friday, April 20, 2012 at 12:41pm.

Consider a wheel (solid disk) of radius
0.748 m, mass 16 kg and moment of iner-
tia 1/2 MR^2 . The wheel rolls without slipping in a straight line in an uphill direction 27 above the horizontal. The wheel starts at
angular speed 20.5882 rad/s but the rotation slows down as the wheel rolls uphill, and eventually the wheel comes to a stop and rolls back downhill.How far does the wheel roll in the uphill
direction before it stops? The acceleration of gravity is 9.8 m/s^2 .
Answer in units of m
