Explain how the coefficient of friction and the angle of an inclined plane affect the magnitude of the friction force acting on an object.
A 20 kg block is sliding down an inclined plane set at 60° with the horizontal. If the coefficient of kinetic friction is 0.3, calculate the acceleration of the block.

Quick comprehension check
“A 25 kg box is placed on an inclined plane that makes an angle of 20° with the horizontal. The coefficient of friction between the box and the incline is 0.15. Calculate the acceleration of the box down the incline. A 10 kg block slides down an inclined plane set at 45° with the horizontal. If the coefficient of kinetic friction is 0.2, determine the acceleration of the block. A 5 kg object is on an inclined plane with an angle of 30° to the horizontal. The coefficient of friction between the object and the plane is 0.3. What is the acceleration of the object down the inclined plane?”
