1

Explain the role of the normal force on an object sliding down an inclined plane. How does it relate to the force of gravity?

2

If an object of mass 10 kg is sliding down an inclined plane at an angle of 30 degrees with a coefficient of kinetic friction of 0.2, calculate the force of friction acting on the object.

Quick comprehension check

An object with a mass of 8 kg is sliding down an inclined plane at an angle of 25 degrees. If the coefficient of kinetic friction between the object and the surface is 0.3, calculate the force of friction acting on the object. Show all work. A 12 kg box is sliding down an inclined plane that makes an angle of 40 degrees with the horizontal. If the coefficient of kinetic friction is 0.25, determine the force of friction acting on the box. Show all work.
