CM: Gravitation and Force Center

  1. May 9, 2006 #1
    I can't seem to figure this one out.
    A particle at rest is attracted to a center of force by the relation
    what is the time it takes for the particle to get to the force center from a distance d in terms of d and k?

    I can't seem to find any equations that will help me out on this one. Thanks PF

    I would like to point you towards Newtons second Law.

    the clue i was given is that energy is constant and equal to the potential enrgy at the initial position
