A particle on a wave starts with a displacement of 3 cm above equilibrium. As the wave moves left at 2 m/s, the particle reaches a maximum displacement of 6 cm below the equilibrium in 0.2 s. (a) Find A, T, w, o, A, k. From this write the equation for D(x, t). (b) Draw a snapshot of the wave at t = 0 and a "history graph" (i.e. graph of D(x = 0, t) vs. t) at x 0. Show 2 cycles and label them appropriately. =
