Mechanics: Why Velocity Matters for Rough Plane Deceleration

[Kajan thana]

If an object is is projected up a rough plane with a velocity. Why don't we take the velocity into account when we are finding out the deceleration?

Velocity and acceleration (deceleration) are totally different things.

my question is does the velocity affect the magnitude of the force

Not for a constant coefficient of kinetic friction.

If you have something moving through air, then the DRAG force is velocity dependent.
