If you need more space than is available, please attach additional sheets of paper. (Modified problem 5.86 from Young&:reedman 12" ed. p.175) ‘Two blocks connected by a massless not-stretchable cord, passing over a massless frictionless pulley, slide to the left on inclined planes as shown in Fig.5.70 (p.175). The coefficient of kinetic friction is 0.05. (a) What is the acceleration of the blocks? Assume $=10 m/s”. (b) Find tension in the cord. Follow the sieps outlined in the Wednesday workshop. The lecture notes outlining the recommended procedure are posted on the course website. L. Sketch the system (copy figure 5.70) and identify parts that you will need to consider when applying Newton's laws. py ey 2. Draw all forces on each block. Are the magnitudes of tension forecs on cach block different or equal? ay 0 3. Set upx-y coordinate system for the first block with the x-axis in direction of its motion. Set up a different coordinate system for the second block with the x-axis in direction of its motion. Indicate the coordinate axes in the figure above (sketch the axis and label them by x,,pr and.x2,y2 respectively. What are the y-components of the acceleration of each block in their reference systems? Physics 211 Spring 2008 Syracuse University Homework Problem Set 6 p.1
