    the horizontal component of a projectile moving with initial velocity of 500 m/s at an angle 60° to x-axis is equal to:

    Draw your x and y vectors along with the velocity vector.

    Don't confuse the terminology. Horizontal and vertical components are properties of vectors. Projectiles are not vectors.

    Also ask yourself,
    What is the value of sin(0)?
    What is the value of cos(0)?

    then find out what balisstic coeficient is, unless your talking about projectiles in space.

    Or projectiles in a homework problem that conveniently ignores select real world conditions.

    Presumably the question asks for components at initial firing.

    it has to travel through the atmosphere, a bullet starts to slow down as soon as it leaves the muzzle, affecting the path of its flight.

    Learn to crawl before walking -- almost all projectile motion studies begin in the absence of friction of any kind. That comes later, and even then it is simplified and ignores other factors that real-world long-range projectile motion problems have to take into account.

    Why make life more complicated than what is necessary?

    Shooting from the hip just two meters away from the target? :p :) Couldn't resist.
