A 880 N crate is being pulled across a level floor by a force F of 385 N at an angle of 27° above the horizontal. The coefficient of kinetic friction between the crate and the floor is 0.25. Find the magnitude of the acceleration of the crate.

2. Relevant equations

Fnet=ma

3. The attempt at a solution

Okay, so I drew out a diagram. You need to find Force Normal in the X direction in order to get FF=coefficientFN, so the equation for the X direction would be FAcosTheta+FN-mg=ma. That eventually turns into FAcosTheta-mg=FN. The problem is, once I plug all the values into the Y equation, the website says I'm wrong. Please help me!
