A 1.80 m string of weight 0.0135 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Ignore the very small variation in tension along the length of the string that is produced by the weight of the string. When you pluck the string slightly, the waves traveling up the string obey the equation y (x, t) = (8.50 mm) cos (172 rad/m x - 4830 rad/st) Assume that the tension of the string is constant and equal to W.

A 1.80 m string of weight 0.0135 N is tied to the ceiling at its upper end, and the lower end
supports a weight W. Ignore the very small variation in tension along the length of the
string that is produced by the weight of the string. When you pluck the string slightly, the
waves traveling up the string obey the equation
y (x, t) = (8.50 mm) cos (172 rad/m x - 4830 rad/s t)
Assume that the tension of the string is constant and equal to W.
