The wave function for a wave on a taut string is y(x, t) = 0.335 sin(9?t ? 3?x + ?/4) where x and y are in meters and t is in seconds. The linear mass density of the string is 91.0 g/m.
(a) What is the average rate at which energy is transmitted along the string?
W
(b) What is the energy contained in each cycle of the wave?
J
