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.

Answer 1

WE CAN INFER THAT IF BOTH THE PERSONS ARE APPLYING FORCE ON TWO OPPOSITE SIDES OF A MOVING CAR, THE NET EFFECT BECOMES LESS. ALSO SINCE THE CAR IS MOVING, IT CONTINUES TO MOVE AT THE SAME SPEED IN THE SAME DIRECTION

Answer 2

Answer:

Explanation:

From the given statement we can infer about the magnitudes and direction of the forces applied that the -  

1. The magnitude of forces will be equal and the same.

2. The forces will also act in the opposite direction.

3. Hence, as a result, both of them cancel out each other and the net effect will shift and thus become less.

Therefore, Two persons are applying forces on two opposite sides of a moving

cart and the cart still moves with the same speed in the same  direction we can infer that both the forces are of equal magnitudes and applied in the opposite directions.
