Maximum possible amplitude of oscillation

  1. Apr 17, 2012 #1
    1. The problem statement, all variables and given/known data
    You stick two blocks together with Velcro. The manufacturer rated the Velcro as needing a force of 50N to seperate the side you are using when applied to solid surfaces. You set up the connected blocks so that the top one is attached to the end of a vertical spring. The blocks each ahve mass m = 0.75kg, and the spring constant is k = 1200N/m. FInd the maximum possible amplitude of oscillation at which the blocks will hold together.


    2. Relevant equations
    not a clue..


    3. The attempt at a solution
    ^^

    The spring is providing a force on the block to keep it oscillating (as it is continually changing speed). You need to find out a which point in the oscillation this force is maximum and then think about what might cause the blocks to separate.
