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

    What is the shortest horizontal distance from a crest to a point of zero acceleration?

    2. Relevant equations


    3. The attempt at a solution

    Dont know how to begin...

    Do you know any calculus?
  4. Feb 27, 2009 #3
    Well I do...kinda. That was a couple of years ago. Except the physics course I am taking is an algebra based course...

    Any other suggestions?

    ok … forget calculus …

    on a graph, what shapes are negative zero and positive acceleration? :smile:

    dietcogekal it may help to think of something like a swinging pendulum.Where in the swing is the acceleration a maximum and where is it zero?

    This is sounding more like simple harmonic motion, and not a wave phenomena problem.

    We really should have an equation describing the motion, to work from ... what does the text book have in the way of equations for this topic?
