Oscillation - car losing contact with bridge

  1. May 28, 2012 #1
    1. The problem statement, all variables and given/known data
    See attachment



    2. Relevant equations



    3. The attempt at a solution

    Ok so as the bridge is at a point ABOVE eqm acceleration is DOWN and at some point ACC down is greater than gravity acceleration.
    This is all true but makes no sense to logically. How could the car lose contact with the bridge at this point. Is the car thrown into the air, or does the bridge simply accelerate DOWN faster than the car

    ok, trying to visuallise this.
    I presume this will though, above eqm, as the bridge moves DOWN towards eqm??
