Two rubber bands

  1. Oct 1, 2009 #1
    1. The problem statement, all variables and given/known data
    Two rubber bands pulling on an object cause it to accelerate at 1.6 m/s2

    (a) What will be the object's acceleration if it is pulled by six rubber bands? Answer: 4.8 m/s/s (correct)
    (b) What will be the acceleration of seven of these objects glued together if they are pulled by two rubber bands?


    2. Relevant equations



    3. The attempt at a solution

    got 4.8 m/s/s for A....that is right...don't know how to get b

    Two rubber bands, one object, a = 1.6 m/s2.

    Two rubber bands, seven objects, a = ?

    When the mass is seven times as big and the force is the same, the acceleration will be ...? Think Newton's Second Law.
