1 of 3 a A farm tractor is accelerating over level ground. The force of friction acting upon the tractor due to the ground is best represented by which vector? 3 2 1 FFr FFr FFr 3
2 of 3 • A farm tractor is pulling a wagon. The tractor is three times heavier than the wagon. The tractor starts from rest and accelerates for a short while. The magnitude of the force with which the wagon pulls on the tractor is • Zero. • One-third of that with which the tractor pulls on the wagon. • Equal to that with which the tractor pulls on the wagon. • Three times that with which the tractor pulls on the wagon. a 4
3 of 3 • A farm tractor is pulling a wagon. The tractor is moving with uniform speed over the level earth. The net force acting upon the wagon is • To the right. • Zero. • To the left. v 5
