Homework Statement
[/B]
A sign with a mass of 27 kg is hanging in two wires both making an angle of 25 degrees with the vertical. Find the tension in one of the wires. Give your answer in Newtons (N) and with 3 significant figures.
Homework Equations
Ftens=gravity/sin(x) ?
The Attempt at a Solution
Force of gravity is 49N, half (finding one wire) is 24.5. The 25 degrees is with the vertical cos(25).
24.5N/cos(25)
This equals 27.0N
The answer should be in the hundreds.
I'm confused on whether I should be using the mass at all, or if I should be converting to Newtons, which would be 264.78, but the division of gravity is already converted to Newtons so I wouldn't see why I'd have to convert it again.
