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.

Answer 1

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

Answer 2

so it should be -1.76 m/s^2

Answer 3

yes, the negative sign indicates direction.
