1. The problem statement, all variables and given/known data A brother and sister try to communicate with a string tied between two tin cans. If the string is 9.5m long, has a mass of 55g and is pulled taut with tension 6N, how much time does it take for a wave to travel from one end of the string to the other? 2. Relevant equations v=√(F/M) M=mass/length t=d/v 3. The attempt at a solution First, I converted 9.5m to 950cm and 55g to .055kg I used these to find M=.055/950 M=5.7* 10^-5 I used F=6N and divided that by M, then took the square root and i got v=321.96 then I divided 950 by 321.96 in order to get the time, and got t=2.95 but this is incorrect.
