**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?

## Homework Equations

mgh=1/2*I*W^2

## The Attempt at a Solution

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.
