Textbook Problem

A taut clothesline has length L and a mass M. A transverse pulse is produced by plucking one end of the clothesline. If the pulse makes n round trips along the clothesline in t seconds, find expressions for (a) the speed of the pulse in terms of n, L, and t and (b) the tension F in the clothesline in terms of the same variables and mass M.

(a)

To determine
The speed of the pulse.

Explanation

Given info: The length of the taut clothesline is L and mass is m . A transverse pulse is produced by plucking one end of the clothesline. The pulse makes n round trips along the clothesline in t seconds.

Explanation:

In one round trip the distance covered by the pulse will be 2L .

In n round trips the distance covered by the pulse will be,

d

b)

To determine
The tension F on the clothesline.
