Student A pulls on a rope attached to a cart with 200 units of force. Student B pushes on a cart with 300 units of force. Student C pushes on the cart with 400 units of force. Will the cart move or remain in one place?
It will move to the left. Student A and Student C 200 + 400 = 600 units of force. Student B-300 units of force: 600 -300 = 300 units of force more.
