【单选题】A person pulls a box across the floor. Which is the correct analysis of the situation?
A.
1. The box moves forward because the person pulls forward slightly harder on the box than the box pulls backward on the person.
B.
Because action always equals reaction, the person cannot pull the box- the box pulls backward just as hard as the person pulls forward, so there is no motion.
C.
The person gets the box to move by giving it a tug during which the force on the box is momentarily greater than the force exerted by the box on the person.
D.
The person’s force on the box is as strong as the force of the box on the person, but the frictional force on the person is forward and large while the backward frictional force on the box is small.
E.
The person can pull the box forward only if he or she weighs more than the box.
