A certain spring has a linear mass density of `0.25 kg m^(-1)` and is stretched with a tension of 25 N. One end is given a sinusoidal motion with frequnecy 5 Hz and amplitude 0.01 m. At time t=0, the other end has zero displacement and is moving in the positive y-direction.
(i) Find the wave speed, amplitude, angular frequnecy, period, wavelength and wave number.
(ii) Write a wave function representing the wave.
(iii) Find the position of the point at x=0.25m at time t=0.1s.
