A bicycle wheel is rolled down a hill that is 8 m high, Determine the linear speed of the wheel at the bottom of the hill if the wheel is moving initially at .5 m/s(adsbygoogle = window.adsbygoogle || []).push({});

I= 1/2mr^2

mgh=1/2mv^2

I know it is set up like a KE equation, and I also know I am missing a variable to solve for on the mgh side. Does anyone know what that variable might be? I know it isn't torque.
