Quick comprehension check
“A block is placed on an inclined plane with an angle of 20° relative to the horizontal. The coefficient of friction between the block and the plane is 0.3. Will the block slide down the plane? Explain your reasoning. A box is placed on an inclined plane with an angle of 35° relative to the horizontal. The coefficient of friction between the box and the plane is 0.7. Will the box slide down the plane? Explain your reasoning.”
