008 (part 1 of 3) 10.0 points A sinusoidal sound wave is described by the displacement s(x, t) = sm cos(kx - wt), where Sm= 4.46 w = 920 rad/s. = k um, 14.9 rad/m, and Find the speed of this wave. Answer in units of m/s. 009 (part 2 of 3) 10.0 points Determine the instantaneous displacement of the molecules at the position x = 0.0715 m at t = 1.55 ms. Answer in units of um. 010 (part 3 of 3) 10.0 points Determine the maximum speed of the molecules' oscillatory motion. Answer in units of m/s.
