A string oscillates according to the equation y´ = (0.635 cm) sin[(π/3.0 cm-1)x] cos[(54.1 π s-1)t]. What are the (a) amplitude and (b) speed of the two waves (identical except for direction of travel) whose superposition gives this oscillation? (c) What is the distance between nodes? (d) What is the transverse speed of a particle of the string at the position x = 1.64 cm when t = 1.42 s?
