A string of length 3 m and total mass 12g is under a tension of 160N. A transverse harmonic wave with wavelength 25cm and amplitude 2cm travels to the right along the string. It is observed that the displacement at x = 0 at t = 0 is 0.87cm. (10marks)
(a) What is the speed of the wave?
(b) Write the wave function, y (x, t).
(c) Find the particle velocity at position x = 0 at time t = 10 s. What is the maximum particle velocity?
