A string oscillates according to the equation   `y' = (0.50 cm) sin [((pi)/(3)cm^(-1))x] cos [(40 pi s^(-1))t]`.   What are the (a) amplitude and (b) speed of the two waves (identical except for direction of travel) whose superposition gives the oscillation? (c) what ist eht distance between nodes? (d) What is the transverse speed of particle of the string at the position `x = 1.5 cm` when `t = (9)/(8)s`?
