Two persons are applying forces on two opposite sides of a moving cart. The cart still moves with the same speed in the same direction. What do you infer about the magnitudes and direction of the forces applied?
Given that two persons are applying forces on two opposite sides of a moving cart. The cart still moves at the same speed in the same direction. This can happen only if the magnitudes of applied forces are equal but opposite in direction so that they cancel each other as illustrated in the diagram below:
