How many wavelengths are on string at any instant of time

Reference no: EM13689937

Solve the all parts of given problem:

Problem: A 1.70-m string of weight 1.40 N is tied to the ceiling at its upper end, and the lower end supports a weight W. When you pluck the string slightly, the waves traveling up the string obey the equation y(x,t) = (8.60 mm) cos(162m1x + 2710s1t).

Part I: How much time does it take a pulse to travel the full length of the string?

Part II: What is the weight W?

Part III: How many wavelengths are on the string at any instant of time?

Part IV: What is the equation for waves traveling down the string?

Show all work, use additional paper if necessary.
