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.
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.”
