“A 25 kg box is placed on an inclined plane with an angle of 20°. The coefficient of static friction between the box and the plane is 0.35. Will the box slide down the plane? Show your calculations. A 10 kg block rests on an inclined plane that makes an angle of 35° with the horizontal. The coefficient of static friction between the block and the plane is 0.6. Will the block slide down the plane? Show your calculations.”
