1

Explain the components of the forces acting on an object placed on an inclined plane. Include the roles of gravitational force, normal force, and friction.

2

A 30 kg mass is placed on an incline that makes an angle of 45° with the horizontal. Calculate the parallel and perpendicular components of the gravitational force acting on the mass.

Quick comprehension check

A 25 kg mass is placed on an incline that makes an angle of 40° with the horizontal. The coefficient of kinetic friction between the mass and the incline is 0.25. Calculate the net force acting on the mass and its acceleration down the incline. Show all work. A 15 kg object is on an incline of 20° with a coefficient of static friction of 0.4. Determine the maximum static friction force that can act on the object before it starts to slide down the incline. Show all work.
