The Gravitron is a ride that rotates around a central axis until it reaches a certain velocity and the riders are pinned to the walls. Once this occurs, the floor is lowered until the riders are suspended above the floor. The Gravitron has a radius of 3.00 meters and reaches a speed of 15.0 m/s. Dalnita has a mass of 55.0 kg. What is her angular velocity in radians per second?

Sounds like you've been given some unnecessary information.

The linear velocity "v" and angular velocity "w" of something in circular motion of radius "R" are related as;

v = Rw

You are given v = 15 m/s and R = 3 m, so just solve for "w".
