I am stuck on this homework question, please make your steps visible and highlight answers.

A transverse wave on a string is described by the following wave function. y = 0.105 sin _x + 3xt 9 where x and y are in meters and t is in seconds. (a) Determine the transverse speed at t = 0.120 s for an element of the string located at x = 1.40 m. m/s (b) Determine the transverse acceleration at t = 0.120 s for an element of the string located at x = 1.40 m. m/s2 (c) What is the wavelength of this wave? m (d) What is the period of this wave? S (e) What is the speed of propagation of this wave? m/s
