A tractor pulls a loaded wagon on a level road with a constant horizontal force of 440 N (▼ Figure 4.8). If the mass of the wagon is 200 kg and that of the load is 75 kg, what is the magnitude of the wagon’s acceleration? (Ignore frictional forces.) 

THINKING IT THROUGH. This problem is a direct application of Newton’s second law. The two separate masses (wagon and contents) make up the system.
