# Finding mass of speaker?

**1. The problem statement, all variables and given/known data**

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

**2. Relevant equations**

F=ma

x=T1sin(x)-T2sin(x)

**3. 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!
