“A 5 kg box rests on an inclined plane angled at 20°. The coefficient of static friction between the box and the plane is 0.3. Will the box slide down the plane? Show your calculations and explain your reasoning. A 2 kg book is placed on an inclined plane. The angle of the incline is adjustable. If the coefficient of static friction between the book and the plane is 0.4, at what angle will the book begin to slide? Show your calculations and explain your reasoning.”
