A 38.5 kg girl and a 57.0 kg boy are on the surface of a frozen lake, 10.0 m apart. Using a rope, the girl exerts a horizontal 5.55 N force on the boy, pulling him toward her. Calculate the magnitude of the girl's acceleration

To calculate the magnitude of the accelerations you can use the formula F=ma. The girl's acceleration is simply 5.55N / 38.5kg = a

A in this instance is .14 m/s^2, I think.
