a window washer weighing 271.8N is standing on a scaffold by a vertical rope at each end. the scaffold weighs 265.6N and is 4.452m long. what is the force in each rope when the window washer stands 1.48m from one end.

Homework Equations

1/2(m1+1/2 m2)Vf^2

The Attempt at a Solution

1/2 (271.8+ 1/2 265.6N)1.48^2
i know this is wrong. i can't find the correct equation to use.

Do you know anything about statics?
You have two unknowns and you need two equations.
It would probbably help you if you would draw a picture. You need to make a free body diagram first.
