**Unformatted text preview: **Again, label the axes completely. (d) Make a plot of velocity squared versus time for two full cycles. Again, label the axes completely. (e) Make a plot of kinetic energy and potential energy on the same graph (make sure you get their relative magnitudes right). Then add to get the total mechanical energy as a function of time. Do the three plots make sense? Distinguish clearly between the three and label the axes completely. (f) Suppose that the initial displacement of the mass was doubled. By what factor would each of the quantities max v , max K , and max U change? (g) Describe the motion qualitatively if there was a little friction between the bottom of the block and the horizontal surface. Qualitatively repeat part (e) for this case....
