A 1.50-m string of weight 1.25 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Assume that the tension on the wire is due to only the weight W, and thus the tension is uniform along the wire. When you pluck the string slightly, the waves traveling up the string obey the equation y(r, t) = (8.50mm) cos(172m-lx– 2730s-lt) (a) How much time does it take a pulse to travel the full length of the string? (b) What is the weight W? (c) How many wavelengths are on the string at any instant of time? (d) What is the equation for waves traveling down the string?

A 1.50-m string of weight 1.25 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Assume that the tension on the wire is due to only the weight W, and thus the tension is uniform along the wire. When you pluck the string slightly, the waves traveling up the string obey the equation y(x, t) = (8.50mm) cos(172m-lr– 2730s-1t) (a) How much time does it take a pulse to travel the full length of the string? (b) What is the weight W? (c) How many wavelengths are on the string at any instant of time? (d) What is the equation for waves traveling down the string?
