A transverse sinusoidal wave on a rope has a wavelength of 0.200 m and travels in the x direction with a wave speed of 0.300 m/s. Its maximum displacement is 45.0 cm. At time t=0.00s an element of the string at x= 0.00 m has a transverse position y = 0.00 cm and is moving with an upward velocity. Write a specific expression for the wave function (include aH numerical quantities for credit!).
