Laura sees a horse pulling a buggy.Which statement best describes the forces acting on the horse and buggy?

A
The net forces exerted on the horse and cart are the same, but the action force is larger.
B
The net forces exerted on the horse and cart are the same, but they are in the same direction.
C
The net forces exerted on the horse and cart are not the same, so the two forces cancel out.
D
The net forces exerted on the horse and cart are not the same, so they are not balanced forces.

Juan inflates a balloon and then releases its end to let the balloon go free as air comes out. The balloon then flies around the room.

A
According to Newton’s first law of motion, the balloon would stay still unless a force caused it to move.
B
According to Newton’s third law of motion, the balloon is pushed forward as the air is forced out.
C
According to Newton’s third law of motion, the balloon resists any change of motion unless an unbalanced force acts upon it.
D
According to Newton’s second law of motion, the balloon exerts a force on the air, which exerts a force back on the balloon.
