## Homework Statement

Forces of 11.8N north, 19.2N east, and 15.9N south are simultaneously applied to a 3.93kg mass as it rests on an air table. What is the magnitude of its acceleration?

What is the direction of the acceleration in degrees? (Take east to be 0 degrees and counterclockwise to be positive. Enter an angle between -180 degrees and +180 degrees.)

## Homework Equations

## The Attempt at a Solution

I was able to find out the answer to the first part of the equation which was 5.0m/s^2 but the angle i Have no idea to get. I just used the tan inverse of my components and got 14.3 degrees but it wasnt right. I also tried -14.3 but no luck there either.

Any help would be appreciated![/B]
