The image shows two opposite forces acting on a rolling cart, what can we say is true about the effect on the forces on the cart
bonufazy [111]

Question options:

1. It cannot be determined without knowing which man is stronger.

2. The forces are unbalanced, and net force on the cart moves it to the left.

3. It cannot be determined because one man is taller than the other.

4. The forces are unbalanced, and net force on the cart moves it to the right.

Answer:

<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>

Explanation:

In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.

It is because the person on the right side exerting force  (50N) toward the left, rolling cart will moves to the left.
