A string oscillates according to the equation below. y = (0.30 cm) sin[(?/3 cm-1)x] cos[(20? s-1)t]
(a) What is the amplitude of the two waves (identical except for direction of travel) whose superposition gives this oscillation?
(b) What is the speed of these waves?
(c) What is the distance between nodes?
(d) What is the transverse speed of a particle of the string at the position x = 1.5 cm when t = 9/8 s?
