2. 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 thehorizontal.
(a) What is the acceleration of each box? (7 marks)
(b) Now consider all surfaces are frictionless. Then calculate the amount of force with direction
to prevent the sliding of the boxes. (3 marks)
Answer to the question is.
