Cathleen is dragging a 110 kg trunk across a rough floor at a constant velocity of 5.6 m/s [E] with a horizontal force of 380 N [E].

a. Calculate the coefficient of kinetic friction between the trunk and floor.

b. Mariam decides to help by pulling on the trunk with a force of 150 N [Up]. Will Mariam be helping Cathleen? Explain.

c. If Mariam, who is 55 kg, stops pulling and sits on the trunk. What force does Cathleen need to pull at now for the trunk to accelerate at 2.0 m/s²?
