Quick comprehension check
“A 20 kg box is placed on a 30° incline. The coefficient of friction between the box and the incline is 0.3. Will the box slide down the incline? Show your calculations and explain your reasoning. A 10 kg block is on a 45° incline. The coefficient of friction between the block and the incline is 0.5. Will the block slide down the incline? Show your calculations and explain your reasoning.”
