A string oscillates according to the equation below.(adsbygoogle = window.adsbygoogle || []).push({});

y' = (0.50 cm) sin[(π/3 cm-1)x] cos[(45π s-1)t]

(a) What are the amplitude and speed of the two waves (identical except for direction of travel) whose superposition gives this oscillation?

cm (amplitude)

cm/s (speed)

(b) What is the distance between nodes?

cm

(c) What is the speed of a particle of the string at the position x = 1.5 cm when t = 9/8 s?

cm/s

i have no clue how to do this problem. any help is greatly appreciated. thanks?
