Forces in Two Dimensions: Net Force and Components

[copypacer]

Homework Statement

If a 1.00 kg body has an acceleration of 9.01 m/s2 at 39° to the positive direction of the x axis, then what are (a) the x component and (b) the y component of the net force on it, and (c) what is the net force in unit-vector notation?

Homework Equations

F=ma?

The Attempt at a Solution

I literally have no idea what to do. Rather than just putting the answer, can you explain in detail as to why you would do "this" in a forces problem like this, and what formulas are usually used in forces (aside from f=ma)

can you at least draw a diagram of what's going on? Without SOME effort on your part, this thread will be closed or deleted.
