Velocity as a function of radial distance on an elliptical trajectory

  1. Jul 1, 2009 #1
    1. The problem statement, all variables and given/known data

    Assume that a point on an ellipse is described by the vector [tex]r=m(a\cos{\theta},b\sin{\theta})[/tex], where [tex] 0\leq m\leq 1[/tex] and that the vector is rotating in the clockwise direction at constant tangential velocity [tex]W[/tex] when [tex]m=1[/tex].

    The problem is to find the velocity [tex]W(m)[/tex].

    Also, is the angular velocity constant as it is for circular motion?

    Did you take the time derivative of it and then calculate the magnitude of dr/dt?
