## Homework Statement

Only two forces act on an object (mass=3.00kg). F1=60.0N 45.0deg above the +x axis, F2=40.0N on the +x axis. Find the magnitude and direction (relative to the x axis) of the acceleration of the object.## Homework Equations

F=ma,

## The Attempt at a Solution

(60.0N)(sin(45))=Fy, Fy=42.4N

(60.0N)(cos(45))=Fx, Fx=42.4N

ay=((60.0N)+(42.4N))/3.00kg

ay=34.13 m/s^2

ax=40.0N/3.00kg

ax=13.3 m/s^2

a=36.6 m/s^2

68.7 deg above +x axis

I can't figure out where I am going wrong.
