Object A is acted on by only object B. The mass of object A is 20.0 kg and its acceleration is 4.00 m/s2 west. Object B is acted on by two forces, the force of object A on object B and another unknown force. If mass of object B is 40.0 kg and the acceleration of object B is 3.00 m/s2 west, what is the unknown force?
