Homework Help: A spring

  1. May 8, 2007 #1
    Determine the motion of this mechanical system-
    *Pic attached*

    satisfying the initial conditions :-
    y1(0) = 1
    y2(0) = 2
    y1'(0) = -2*sqrt(6)
    y2'(0) = sqrt(6)

    I need to find equations for y1(t) and y2(t). Please help :D

    PS ideal springs, point masses cannot collide, y1 and y2 are the distances of the bottom end of the springs from the top, so that the length of the second spring is y2-y1. As for gravitational effects, gravity pulls on the weights to start the springs moving, but you don't need to deal with gravity in your calculations.

    No one helps maybe because you did not show us your work so far, equations you know etc.
