Calculating Angular Velocity of a Rolling Sphere on an Inclined Plane

[alex7298]

Homework Statement

so i need to find the angular velocity of a solid sphere rolling down an inclined plane. I know the mass, radius, and distance the sphere travels.

Homework Equations

The Attempt at a Solution

I know how to get angular velocity, but i need the translational velocity first (m/s). Do i use d=v/t or d=1/2(Vi-Vf)(t) which should go down to v=2d/t. I am getting like 61rad/s and after talking to some other people, they said that was too big. They are getting theirs to be under 1...which doesn't make sense to me

and i know the time it takes. And i meant to say v=d/t above

i need this tonight
any help would be great!
thanks
