(b) The (transverse) speed of a point on the cord is given by taking the derivative of y : u ( x, t ) = ∂y ∂t = − ωy m cos( kx − ωt ) which leads to a maximum speed of u m = ωy m = (2510 rad / s)(0 . 020 m) = 50 m / s. (c) The speed of the wave is v = λ T = ω k = 2510 rad / s 62 . 8 m − 1 = 40 m / s ....
