You are given a vector in the xy plane that has a magnitude of 95.0 units and a y component of -40.0 units. What are the two possibilities for its x component?

• Physics -

the x component will be +- sqrt (95^2-40^2) according to Pythagoras

• Physics -

how did you get that as the answer though??

• Physics -

and wat is this +-sqrt thing mean?

• Physics -

Have you ever heard of Pythagoras and his theorem on right triangles? sqrt means square root.

I am wondering how one does vectors in the Cartesian plane without Pythagoras? Even Rene Descartes used it.
