Homework Statement
Starting from rest, a spinning compact disk undergoes an angular acceleration of 5.0 rad/s^2. What is the angular speed of the disk after 3 revolutions?
Homework Equations
a=Δω/Δt
ω=Δθ/Δt
The Attempt at a Solution
I do not understand how to solve this equation when I am not given a time. I don't have a radius, so I can't find the circumference either. How can I solve this?
