Q2. Passengers standing in a bus are thrown backward when the bus suddenly starts. According to the book, the reason is that
- a backward force acts on the passengers as soon as the bus starts
- friction between the feet and the floor of the bus is zero at that instant
- the reaction of the bus on the passengers is greater than the action
- their feet are carried forward with the bus by friction while the rest of the body tends to stay where it was due to inertia
Show answer
Correct answer: D. their feet are carried forward with the bus by friction while the rest of the body tends to stay where it was due to inertia
