Angular speed of rotation

salaam

1. The problem statement, all variables and given/known data

In an amusement park rocket ride, cars are suspended from L = 4.19 m cables attached to rotating arms at a distance of d = 6.05 m from the axis of rotation. The cables swing out an angle of theta = 46.7 degrees when the ride is operation. What is the angular speed of rotation?

2. Relevant equations
Ac=V^2/r (maybe?)

3. The attempt at a solution
I have no idea where to start. i'm in major need of help
