Suppose a 68-kg boy and a 40-kg girl use a massless rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.0 m/s^2, find the magnitude of the acceleration of the boy toward the girl.

    Fboy+Fgirl=0
    68*a+40*3.0=0
    solve for a.

    so it should be -1.76 m/s^2
