1. The problem statement, all variables and given/known data The wave speed in a guitar string of length 62.9 cm is 278 m/s. you pluck the center of the string by pulling it up and letting go. Pulses move in both directions and are reflected off the ends of the string. If you plucked the string 25.1 cm from the left end of the string, how far from the other end of the string would the two pulses meet? In units of cm. 2. Relevant equations I thought just some old-fashioned algebra could do it.. 3. The attempt at a solution What I first tried was 25.1 cm + x= Remainingcm-x, so: 25.1cm+x=(62.9-25.1)-x 25.1cm+x=37.8-x 2x=12.7 x=6.35 cm However, this did not work. Can anyone tell me what I'm doing wrong? Thanks.
