A cord of mass .65 kg is stretched between two supports 28 m apart. If the tension in the cord is 150 N, how long will it take a pulse to travel from one support to the other?

2. Relevant equations

umm... the only equation to find helpful was...

T = 2pi[tex]\sqrt{m/(mg/L)}[/tex] = 2pi[tex]\sqrt{m/(F/L)}[/tex]?

3. The attempt at a solution

Knowns:

F (tension) = 150 N

m = .65 kg

L = 28 m

2pi[tex]\sqrt{.65 kg/(150 N/28 m)}[/tex] = 2.19 s?

Though the book says it is 35 s...

Help? Should there be another equation that I should be using or did I miss something?
