Homework Statement
A speakerh angs from the ceiling by a pair of wires, as showin the diagram below. the tension in wire 1 is 35N. What is the mass of the speaker?
Given from the problem and picture.
Wire1=25 degrees
Wire2=55 degrees
Tension in wire1= 35N
Tension in wire2=18.02N
Homework Equations
F=ma
x=T1sin(x)-T2sin(x)
The Attempt at a Solution
This is what I got but didn't get full points becasue I am missing the Y component?
x=35sin(25)-T2sin(55)
T2=35sin(25)/sin55
T2=18.05
Then we used this equation
T1y+T2y-mg
0=T1y+t2y-m(9.8)
Rearange and plug in numbers:
35+18.05/9.8
m=5.41kg
She told me I am right all the way up to the last part (35+18.05/9.8) and was told I'm need the y-components..but I solved for it?
Thank you!
