Question

S5. At right is a snapshot at t 0 of a wave traveling to the right on a string. The string is tied to the wall at x-6 m. The wave moves at v 1 m/s. A point P is indicated on the axis. a) Sketch the appearance of the wave at t -4 s.(2 marks] b) Sketch the history graph for the point P. Show enough time that everything interesting that happens at Pa shown. [2 marks] S6. Two masses, m, and ma, are hung from identical springs (ie. the stiffnesses, k, of the two springs are the same and the unstretched lengths of the springs are also the same). However when we hang the two masses we find that m; hangs stationary at a lower height than m, does, k as shown. The position as a function of time for m, is shown on the following graph. Suppose that m, oscillates with the same amplitude. On the graph sketch what the position as function of time for m, might look like. Briefly explain your reasoning.
