pls mark as brainliest and follow me plsss....
1 dust particle is at rest on carpet. however when you beat a carpet you are forcing the dust to move along with the carpet. due to the dust having inertia which does not move or rather it resist motion. this is why dust come out of the carpet when it is beaten with a stick.
2. without a mudguard the mud and Debris would be continue and possible cause a problem for the car behind .
one more answer of it is related to Newton's Law of Motion .
