I did an experiment in which a cart on wheels is getting pulledby a pulley hanging off the surface. The pulley has a 50g hangerwhich causes the motion. The cart is 300g and then in differenttrials added one 50g weight, two, three, and then four. The slopewas 0 degrees. My question is: Describe (and show with pictures)what forces change for each of the different configurationsused.
