Question: Two strings, each 15.0 m long, are stretched side by side. One string has a mass of 78.0 g and a tension of 180.0 N.

Two strings, each 15.0 m long, are stretched side by side. One string has a mass of 78.0 g and a tension of 180.0 N. The second string has a mass of 58.0 g and a tension of 160.0 N. A pulse is generated at one end of each string simultaneously.

(a) On which string will the pulse move faster?

(b) Once the faster pulse reaches the far end of its string, after what additional time interval will the slower pulse reach the end of its string?
