1. The problem statement, all variables and given/known data String 1 in the figure has linear density 2.4 g/m and string 2 has linear density 3.5 g/m. A student sends pulses in both directions by quickly pulling up on the knot, then releasing it. Consider the pulses are to reach the ends of the strings simultaneously. In the figure: The two strings are tied together in the middle and the combined strings have a length of 4m. 2. Relevant equations What is the length of string one and what is the length of string 2?
