Pre-reading question: Find the x and y components of the Normal Force in this diagram: (For some reason, friction in this digram is labeled “Fr.”)
Post-reading question: Using the diagram in the pre-reading question, assume the angle is 15 degrees and the mass of the block is 20kg. Find the x and y components of both the normal force and friction (which in the diagram is strangely labeled “Fr”). Be careful, your pre-reading answer might have been incorrect, so be sure to apply what you learned in the video.
