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 the following.
(a) the expression for the speed of the pulse in terms of n, L, and t
b) the expression for the tension F in the clothesline in terms of the same variables and mass M
