A wave on a string is described by the relation y =0.15 sin(200πt -0.045x), where t is
measured in seconds and x in meters.
(a) What is the time required for a single wavelength to pass a fixed point by the wave?
(b) What is the maximum speed of a point on the string?
(a) "T=1\/\\nu=2\\pi\/\\omega=2\\cdot\\pi\/(200\\pi)=0.01(s)"
(b) "v=dy\/dt=0.15\\cos(200\\pi t-0.045x)\\cdot200\\pi=94.25\\cos(200\\pi t-0.045x)"
"v_{max}=94.25(m\/s)"
