1. The problem statement, all variables and given known data
A solid disk of radius 1.60 m and mass 2.30 kg rolls without slipping to the bottom of an inclined plane. If the angular velocity of the disk is 4.9 rad/s at the bottom, what is the height of the inclined plane?
mgh=1/2*I*W^2
i tried using conservation of energy
2.3*9.81*x=.5*(2.30*1.60^2)*4.99^2
x=3.19
but that is incorrect.
