Answer:
\mu_(k)

Step-by-step explanation:

We use kinetic friction when a body is moving i.e.
\mu_(k) for calculations.

Static friction is used when a body is in rest while kinetic friction is used when a body is moving and its value is quite low as compared to static friction .

Static friction value increases as we apply more force while kinetic friction occurs when there is relative motion between bodies.
