Using two spring scales, students pull on opposite sides of a dynamic cart at rest. 7 newtons of force is pulling left and 5 newtons force is pulling right. describe the motion of the cart?

The cart would be moving to the left, don't know if you needed this to but by 2 newtons of force

7 newtons of force to the left                           5 newtons of force to the right

                                     7NL - 5NR = 2NL

                            NL=newtons to the left   NR= Newtons to the right

                    i was to lazy to spell it out.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
