QUESTION $1-$ Chapter $12$: Kinetics of Particles

A $120$ kg ammunitions box is sitting on an inclined plane as shown in the figure below. One of the military commanders is attempting to push the ammunitions box up the incline by applying a pushing force, F$.$ The coefficient of static friction $({}_s)$ between the box and the surface of the incline is $0\mathrm{.}4$ and the coefficient of kinetic friction $({}_k)$ is $0\mathrm{.}2.$

$$

What is the force, F $,$ required to prevent the box from sliding down the incline if the angle of incline, $=35?$
