Friction on Inclines

“A block of wood with a mass of 2 kg is placed on an inclined plane angled at 20°. The coefficient of static friction between the block and the plane is 0.3. Will the block slide down the plane? Show your calculations to justify your answer. A metal box with a mass of 5 kg rests on an inclined plane angled at 30°. The force of gravity acting parallel to the incline is calculated to be 24.5 N. If the force of static friction is 20 N, will the box slide down the plane? Explain your reasoning.”
