Question
A 50-kg student pushes on a 2-kg box that moves at a constant speed along a smooth surface, as shown.
Which of the following corresponds to a Newton's third law force pair?
the push on the box by the student and the push on the student by the box
the friction between the box and the surface, and the horizontal component of the push on the box
the normal force on the box and the weight of the box
the weight of the box and the weight of the student
the vertical component of the push applied by the student and the weight of the box
there are no force pairs because the acceleration of the box is zero
Explanation / Answer
from Newton's third law states that for every action there is an equal and opposite reaction.Therefore answer for force pair is a)the push on the box by the student and the push on the student by the box.
