Homework Help: Moment of Inertia and velocity

  1. Nov 15, 2011 #1
    1. The problem statement, all variables and given/known data
    I was doing a experiment in class where I pretty much had to roll cylinders down a surface with a certain angle and then calculate the moment of inertia. After that, the teacher asked me to prove why moment of inertiea doesn't depend on the cylinder's velocity and I just can't figure it out. So I was hoping someone here could help me out :)


    2. Relevant equations
    a=2*l/t^2
    v=a*t=2l/t
    I=m*r^2((g*t^2*sinα)/(2*l)-1)


    3. The attempt at a solution
