Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

An empty box is travelling on the conveyor with 0.2 m/s, then 12 kg package is dropped into this box with 1 m/s speed. When dropped, package and box are immediately sticked together. Friction coefficeient between the box and the conveyor is μk = 0.2 . After the package dropped, package and box start sliding on the conveyor for some distance, d for t(sliding) amount of time. Determine the distance, d.
