# Is my teacher wrong? Problem dealing with forces.

## Homework Statement

Problem is in the picture

## Homework Equations

The teacher told us the
Fnetx = 20N - Fx (Fx is 0)
Fnety = Fy - 50N (Fy = +25N)

## The Attempt at a Solution

My answer was 32N. But my teacher said the answer was C. which was 77.5N. He got it because Fnety = 75N for him. But that to me doesn't make sense since the Fy and 50N are pointing in opposite directions, won't Fnety be = -25N?

Oh nvm i think i got it. I think he meant to put that:
25N = Fy - 50 huh? Darn and to think i could prove a teacher wrong ;"D
