Physics please help!!
A 43.3 kg boy and a 60.0 kg girl are on the surface of a frozen lake, 10.5 m apart. Using a rope, the boy exerts a horizontal 5.90 N force on the girl, pulling her toward him. Calculate the magnitude of the boy's acceleration.

The magnitude of the boy's acceleration is 0.031 m/s^2. This is because the net force on the boy-girl system (the boy pulling the girl toward him and the girl pulling the boy toward her) is 93.3 N, and when this force is divided by the combined mass of the boy and girl (103.3 kg), the result is the acceleration of the system, 0.031 m/s^2. Since the boy has a greater mass than the girl, his acceleration is less than the girl's.
