Quick comprehension check
“A block with a weight of 10 N is placed on an inclined plane with an angle of 20°. The coefficient of static friction between the block and the plane is 0.35. Will the block slide down the plane? Show your calculations and explain your reasoning. An object is placed on an inclined plane with an angle of 30°. The coefficient of static friction between the object and the plane is 0.5. What is the minimum weight (in Newtons) the object must have for it to remain stationary on the incline? Show your calculations and explain your reasoning.”
