## Homework Statement

Two forces, F1 and F2, act on a 2.00 kg object where F1 = 30.0 N (on the x-axis) and F2 = 10.0 N. A 60 degree angle is between them. Find the magnitude and direction of the acceleration.http://www.webassign.net/pse/p5-15.gif (ignore figure a)

## Homework Equations

F=ma

a=sqrt. (ax^2 + ay^2)

## The Attempt at a Solution

I figured out that the magnitude is a=sqrt. (ax^2 + ay^2)

which is equal to 17.67

however i can't get the correct direction! i thought it would be theta = arctan (2.5 /17.5)= 8.13 but it keeps saying its not the right answer! help
