Particle moves in a plane, and i've found that x.n=k

  1. Mar 19, 2006 #1
    Hi people, could someone plz help with the following:

    If a particle moves in a plane, and i've found that x.n=k where n=w/|w|, then how do i go about showing that the particle moves in a circle?

    A fly moves with constant speed v along the spoke of a wheel rotating with angular speed w. Starting from the center of wheel at time t=0, find it's distance at t. Show that the angle theta made between the spoke and the original direction is wt.

    Any help would be welcome, cheers,
