Santa Claus tries to drag his bag of presents along a horizontal surface by a red rope that is angled at
55 degrees above the horizontal. Santa Claus applies a force due to tension of 4500N along the red
rope. This is the minimum force to just start the bag in motion. The coefficient of kinetic friction
between the bag and the ground is 0.3 and the coefficient of static friction is 0.5. What is the mass of
the bag?
