Question
 
Box 1, a wooden box, has a mass of 8.60 kg
and a coefficient of kinetic friction with the
inclined plane of 0.35. Box 2, a cardboard box,
sits on top of box 1. It has a mass of 1.30 kg.
The coefficient of kinetic friction between the
two boxes is 0.45. The two boxes are linked by
a rope which passes over a pulley at the top of
the incline, as shown in the diagram. The inclined plane is at an angle of 38.0° with respect to the
horizontal.
 
 Now consider all surfaces are frictionless. Then calculate the amount of force with direction
to prevent the sliding of the boxes.
 
m1 = 8.60 kg
m2 = 1.30 kg
HA = 0.35
