Question
A string of length 15 cm is stretched between two points as shown in Figure 1. A point P on the
string 5 cm from the point B is deflected a distance 5 cm from its position of rest perpendicular to
AB and released with zero velocity. What are the initial conditions and boundary conditions for
the problem? [Hint: initial conditions = u(x, 0) and ut(x, 0), boundary conditions = u(0, t) and
u(L, t)].
Provided that the wave equation model for the problem mentioned above is utt = 3uxx for
(0<x<L, t> 0). Compute the general displacement u(x, t) of any point at any time, t in
seconds, for all cases using method of separation of variables.
