Fnet=MA problem

  1. Oct 11, 2009 #1
    1. The problem statement, all variables and given/known data

    Suppose that a net force F gives an object with a mass of m an acceleration of 9.70 m/s/s.

    Suppose that the mass were increased by a factor of 7.0. The new acceleration would be ___ m/s/s

    2. Relevant equations

    fnet=Mass*acceleration

    3. The attempt at a solution

    well i know that fnet=MA is the formula to use but don't know how to interperet it if a factor changes

    thanks :)

    Mass does not effect acceleration.

    Hint: its a very simple problem.

    This is not true at all.

    If the force is constant, and your new m' = 7m, what must a' = so that the force remains hte same?
