1. The problem statement, all variables and given/known data A bird is able to go in a circle because it tilts its wings by theta degrees using a lift force, F. So it curves and eventually forms a full circle. if radius is 30m and the bird's velocity is 6m/s what is that tilt angle. 2. Relevant equations 3. The attempt at a solution I calculated stuff like the period and centripetal acceleration, but i'm not even sure if those are needed for this.
