and = v Lf L λ= . (a) Comparing the given function with Eq. 16-60, we obtain k = π /2 and ω = 12 π rad/s. Since k = 2 π / λ then 2 4.0m 4.0m. 2 L ππ = ¡ ¡ = λ (b) Since = 2 π f then 2 12 rad/s, f π= π which yields 6.0Hz 24m/s. fv f = ¡ = (c) Using Eq. 16–26, we have 200 N 24 m/s /(4.0 m) v m τ μ = ¡ = which leads to m = 1.4 kg.
