A 20 kg box is placed on an inclined plane with an angle of 20°. The coefficient of friction between the box and the plane is 0.3. Will the box slide down the plane? Show your calculations and use a diagram to support your answer. A 100 kg crate is placed on an inclined plane with an angle of 45°. The coefficient of friction between the crate and the plane is 0.8. Will the crate slide down the plane? Show your calculations and use a diagram to support your answer.
