Inertia of Motion:
When an object is at rest, it tends to stay at rest, and when it is in motion, it tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This property of objects is known as inertia of motion.
Explanation:
When we strike a hanging carpet with a stick, several things happen that cause dust particles to come out of the carpet. Let's analyze each option to understand the phenomenon:
A. Carpet starts moving forward and backward due to inertia of motion:
This option suggests that the carpet starts moving forward and backward due to its inertia of motion. However, this is not correct because the carpet does not move significantly when struck with a stick. It may vibrate or oscillate slightly, but it does not move back and forth significantly.
B. Dust particles remain at rest:
This option states that the dust particles remain at rest. Dust particles are usually settled on the surface of the carpet due to gravity, and they do not have any significant motion or inertia. Therefore, this option is correct because the dust particles do not move on their own.
C. Dust particles start moving forward due to inertia of motion:
This option suggests that the dust particles start moving forward due to their inertia of motion. However, dust particles do not have any significant inertia of motion. They remain at rest unless acted upon by an external force. Therefore, this option is incorrect.
D. Carpet remains at rest:
This option states that the carpet remains at rest when struck with a stick. While the carpet may vibrate or oscillate slightly, it does not move significantly from its original position. Therefore, this option is correct.
Conclusion:
When we strike a hanging carpet with a stick, the dust particles come out of the carpet because the carpet remains at rest, and the dust particles, being settled on the surface, are dislodged due to the impact of the strike. The dust particles do not have any significant motion or inertia of their own.

This is because when we hit a carpet the carpet starts moving forward and its inertia of rest changes into the inertia of motion but the dust particles which are there with the carpet they move just because of the carpet but actually the particles remain at rest that is why these particles fall of due to the change of inertia.
