Q1:

At what speed does the wave propagate?

What is the maximum speed of the string perpendicularly to the direction of the motion?

Q2:

A piano wire has a linear mass density kg/m. Under what tension must the string be to generate waves that propagate with a speed of 553 m/s?

Q3:

A cord has a linear mass density and a length of 3.0 m. The cord is plucked and it takes 0.20 s for the pulse generated to reach the end of the string. What is the tension of the string?
