Transverse waves on a srting have speed `12.0 m//s`, amplitude `0.05 m` and wavelength `0.4 m`. The waves travel in the `+ x-direction` and at `t = 0` the `x = 0` end of the string has zero displacement and is moving upwards.  (a) Write a wave function describing the wave.  (b) Find the transverse displacement of a point at `x = 0.25 m` at time `t = 0.15 s`.  ( c ) How much time must elapse from the instant in part (b) until the point at `x = 0.25 m` has zero dispacement?
