1. Explain how the coefficient of friction and the angle of an inclined plane affect the magnitude of the friction force acting on an object.
2. 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.
3. A box is placed on an adjustable inclined plane. Describe how you could experimentally determine the angle at which the box begins to slide, and how this relates to the coefficient of static friction.
