Homework Statement
If you were given the
- linear density 1 = 2g/m
- linear density 2 = 4g/,
- total length of the strings = 4m
- Length 1 > Length 2
- the fact that when a pulse is sent from a knot in the strings it reaches the ends at the same time
How would you go about working out the length of each string?
The Attempt at a Solution
I've been trying to use
μ = m/l
v = (T/μ)^0.5
v = s/t
I tried equating the times as they should be the same, but I get stuck after some substitution.
Any ideas?
Thanks
