The figure shows two packages that start sliding down a 20° ramp from rest a distance d = 7.0 m along the ramp from the bottom. Package A has a mass of 2.5 kg and a coefficient of kinetic friction 0.20 between it and the ramp. Package B has a mass of 8.0 kg and a coefficient of kinetic friction 0.10 between it and the ramp.
What is the force of friction, in Newtons, on the 2 boxes. Give your answer in the format: (friction on A, friction on B)
What is the acceleration of box B as it slides down the ramp?
What force does box A exert on box B as they slide down the ramp?
How long does it take box B to slide down the ramp?
