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/s2, find the magnitude of the acceleration of the boy toward the girl.

Is it possible they don't want the negative sign? Is is possible they only want two significant digits?

My crystal ball is not working. I know physics, but I can't guess what the author supposed was the "right" answer.

okay i changed it they didn't want a negative sign for some reason

if arnold strongman and suzie small each pull very hard on opposite ends of a massless rope in a tug-of-war the greater force on the rope is exerted by ? i think both the same
