The FedEx and UPS boxes have almost reached the top of the inclined plane they have been moving along and are now arranged The UPS box has a mass of 3.0 kg, and the FedEx box has a mass of 1.0 kg. The inclined plane is frictionless; however, the horizontal floor has coefficients of static and kinetic friction of 0.5 and 0.2. The pulley is frictionless, and the masses of the pulley and cord are negligible. Answer the following about this system. a.What is the size of the normal force on the UPS box? b. This system will begin to move if released from rest. However, if you pressed with a downward force on the FedEx box, this system could remain at rest. What size force is required? Your solution should include two free-body diagrams. c. If the system was set into motion down the ramp, without the force mentioned in the previous part, what would be the acceleration of the system? Your solution should include two free-body diagrams.
