In an amusement park rocket ride, cars are suspended from L = 4.28-m cables attached to rotating arms at a distance of d = 6.10 m from the axis of rotation. The cables swing out at an angle of θ = 52.0° when the ride is operating. What is the angular speed of rotation?
You know the forces working are mg downard, and centripteal force outward.
