You want the expression for the acceleration of a point on the edge of a frisbee (flying, rotating disk) in flight relative to yourself. If you know the acceleration of the frisbee's center of mass relative to yourself and the position of your point of interest on the frisbee's edge relative to the frisbee's mass center at a particular instant, what other information would you need? nothing - you have all the information you need the frisbee's angular acceleration the frisbee's angular velocity the frisbee's angular velocity and angular acceleration2.3.16.
