Homework Help: Two objects on different concentric circular traks (relative period)

  1. Oct 20, 2012 #1
    Given two particles A and B realizing circular motion respectively on circles with same center o and of radii RA and RB where RA<RB. There angular velocities wA and wB are constant and initially the two objects form an angle θ.
    How long should the object A waits before he crosses object B?

    Thanks for replying, I've done this;



    I need to compute the period for the two objects to meet knowing that wa≠wb and that initially they form angle θ.
