उत्तर
- Luggage is usually secured with a rope to the roof of buses. When a moving bus comes to an abrupt stop, the luggage on its roof tends to remain in motion due to inertia.
- As a result, the luggage falls from the roof of the bus. Similarly, when a bus suddenly starts, the luggage on the roof of the bus tends to remain in a position of rest and so slides off the roof.
- Thus, to prevent the luggage from dropping, it is attached with a rope to the roof of a bus.
