Two blocks are touching each other on the horizontal aluminum track shown in the figure. Block 1 has a mass of 1.34 kg and is an unknown material; Block 2 has a mass of 712 g and is made of felt. As you watch, the blocks (which stay in contact with each other the entire time) accelerate to the right at 1.28 m/s. As this happens, a rope is pulling on Block I with a force of 8.24 N at an angle Orope 31.6 above horizontal. (a) Draw and clearly label a two separate complete free body diagrams for the two boxes. Make sure both diagrams are separate from each other, and very clearly labelled. (You may not draw them on the given figure, since these must be two separate diagrams.) You may not use the same labels for forces that have different magnitudes. Beside the free body diagram, clearly indicate the coordinate system you are using in this problem. (b) Do any of the forces you drew in part (a) form an action-reaction pair? If so, clearly list all action-reaction pairs. (c) Using Newton's Second Law, calculate the magnitude of the normal force on block 2 from block 1.
