A hoop with a radius of .5m and mass of .2kg is released from rest and rolls down inclined plane. How fast is it moving after dropping from vertical distance of 3m? First I tried v=Iw/md but I had no info for angular velocity so I tried calculating using v=sq root 2xgxh and get 7.7m/s but my online test is saying it is wrong. Am I using the wrong formula?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
