A non-extensible string with mass per unit length pt is extended along the z-axis. The string carries a tension T. It undergoes transverse motion described by the function y(x, t). This function y(t) satisfies the wave equation 82y 8t2 v2 8y 82 with v Which of the following statements is correct? Select one or more: y(x, t) is the equation of motion of the physical system specified in the problem The wave equation is the equation of motion of the physical system specified in the problem. The transverse displacement of the string as function of time, specified by function y(t), may also be referre solution of the equation of motion. The wave equation is referred to as the solution of the equation of motion. Mathematically speaking, if the position profile of the entire string is specified at an initial time, then the wa has a unique solution. Mathematically speaking, if the position profile and velocity profile of the entire string is specified at an ini the wave equation has a unique solution.
