3. Use your data from Part 3 and Newton’s laws to explain why the force meter measures a force if the cart is moving at a constant velocity. You should cover the following points. • State Newton’s first law. • Identify the forces acting on the cart. • Describe the relationships between applied force and mass and between applied force and weight as linear (from data or mathematical derivation by applying Newton’s first law). • Explain why the data are linear in terms of Newton’s first law. • Graph F versus mass + cart.

For the problem, I already stated Newton's first law, I just need to do everything else, except the last part.  I know how to graph.

would one  of the forces acting on the cart be the downward force of the weight on the cart?  I attached a picture of the cart.
