Homework Statement
The figure shows two masses hanging from a steel wire. The mass of the wire is 60.5 g . A wave pulse travels along the wire from point 1 to point 2 in 24.0 ms .

//What is mass m?
Homework Equations
mass/(length of wire)=linear density
velocity=sqrt(Tension/Linear density)
sin(theta)*tension=downward force of weight
distance/time=velocity
The Attempt at a Solution
.0605kg/8meters=.00756 linear density
4m/24ms=166.7m/s
166.7m/s=sqrt(Tension/.00756)
27777.8=tension/.00756
210=tension now I get stuck here...
Sin(40)*210=135
135/9.8=14 which is not the right answer is it 7 each and 14 combined Thank you for any assistance I know I'm not super far off just missing how to translate tension force in the whole string into downward force of both those weights
