Two strings, each 19.5 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 152.1 N. A pulse is generated at one end of each string simultaneously. Once the faster pulse reaches the far end of its string, how much additional time will the slower pulse require to reach the end of its string? ms
