A 39.9 kg girl and a 57.4 kg boy are on the surface of a frozen lake, 10.0 m apart. Using a rope, the girl exerts a horizontal 5.60 N force on the boy, pulling him toward her. Calculate the magnitude of the girl's acceleration.

Acceleration of girl=0.140m/s^2

T = F. The tension in the rope is 5.60 N. The tension is the force that pulls on both equally. So assuming no friction

a = F/m
