2 What is the net force on a bag pulled down by gravity with a 30 N force and pulled up by a rope with a 30 N force?

3. The sketch below shows a plank (painter's scaffold) in equilibrium. If the person has a weight of 500 N, and the tension in the ropes is 300 N each, what is the scaffold's weight? Explain Briefly.

4. The weights of Burt, Ernie, and the plank produce tension in the ropes. Rank the tension in the RIGHT rope from greatest to least in the following situation
