1

Explain how the angle of inclination affects the frictional force acting on an object on an inclined plane. Include a description of the forces involved.

2

A 30 kg mass is placed on an incline that makes an angle of 45° with respect to the horizontal. The coefficient of friction between the mass and the incline is 0.3. Calculate the acceleration of the mass down the incline.

Quick comprehension check

A 40 kg mass is placed on an incline that makes an angle of 25° with respect to the horizontal. The coefficient of friction between the mass and the incline is 0.15. Calculate the acceleration of the mass down the incline. Show all work, including a free-body diagram. A 60 kg mass is placed on an incline that makes an angle of 35° with respect to the horizontal. The coefficient of friction between the mass and the incline is 0.25. Calculate the acceleration of the mass down the incline. Show all work, including a free-body diagram.
