A transverse wave is propagating along a certain string. The wave speed is u= 10m s".One end of the string is given a sinusoidal motion with frequency 5Hz and amplitude 0.01m. At time t= 0 the end has zero displacerment and is moving in the +y direction. (a) Write a wave function describing the wave. (b) Find the position of the point at x = 0.25m at time t = 0.1s. ()Find the transverse (vibrational) velocity of the point at x = 0.25m at time t = 0.1s.
