“A 20 kg box is placed on an inclined plane that makes an angle of 20° with the horizontal. The coefficient of friction between the box and the incline is 0.3. Will the box slide down the incline? Show your calculations to justify your answer. A 30 kg block is placed on an inclined plane that makes an angle of 40° with the horizontal. The coefficient of friction between the block and the incline is 0.5. Will the block slide down the incline? Show your calculations to justify your answer.”
