(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A thin, 100.0 g disk with a diameter of 8.00 cm rotates about an axis through its center with 0.150 J of kinetic energy.

What is the speed of a point on the rim?

3. The attempt at a solution

1/2mv^2 = 0.15

v = 1.73m/s

I know

Vt = angular velocity x r

I am not sure how to solve foe the angular velocity
