A tractor pulls a loaded wagon with a constant force of 300 N. If the total mass of the wagon and its contents is 275 kg, (a) what is the wagon's acceleration? (b) Assuming the wagon started from rest, how far does the tractor travel in 4.00 s?

If there is no retarding force, then
net force=m*a
pulling forceretarding force=ma
3000=275*a solve for a
distancethen=a*time
