How to Calculate the Required Force to Move a Block Up an Incline

[Almost935]

Homework Statement

4.00-kg block rests on a 30.0° incline as shown in the figure. If the coefficient of static friction between the block and the incline is 0.700, what magnitude horizontal force F must act on the block to start it moving up the incline?

Homework Equations

F=ma F_friction=μ_sF_normal

The Attempt at a Solution

Numerous attempts to long to type out.

The forces acting on it are its weight and the friction force. A body will not move until the maximum static force is applied on it. Now think what should be the ''minimum'' F to move up the incline so that it overcomes the weight and static friction.

Need more relevant equations (Fn ?)
And at least one attempt. Take what you think is the best and show where it gets stuck.
