7 questions

1

Explain in your own words how the force of gravity acting on an object on an inclined plane is resolved into components. Why is this necessary for calculating the force of friction?

2

Draw a free body diagram for a box sliding down an inclined plane. Label all forces acting on the box.

Quick comprehension check

A 3.0 kg block is on an inclined plane angled at 20°. The coefficient of kinetic friction between the block and the plane is 0.35. Calculate the force of kinetic friction acting on the block. Show your work. A box slides down an inclined plane angled at 35°. The normal force acting on the box is 45 N, and the coefficient of kinetic friction is 0.28. Calculate the force of kinetic friction acting on the box. Show your work.
