Which of the following does not happen? As an automobile accelerates suddenly,a)a toy monkey hung from the roof moves backb)a standing person gets pushed backc)a bag at the roof gets displaced backwardd)a person in the seat is pushed in frontCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

It's option d.
as it does not follow Newton's law of motion

Answer

Correct option is d because as we have seen in case of inertia that the tendency to remain at remain at rest or or to keep moving with same velocity is know as Inertia but when the car acceleration that mean when car starts how can a person pushed In front , a person can be only pushed in front in car when brakes are applied but in this situation the car starts accelerating it not written that brakes are applied in all the situation can be possible but the last one is not possible

Answer

Explanation:
When an automobile accelerates suddenly, there are several physical phenomena that occur due to the change in velocity. Let's analyze each option to determine which one does not happen.

a) A toy monkey hung from the roof moves back:
When an automobile accelerates suddenly, the passengers and objects inside experience a backward force due to inertia. Inertia is the tendency of an object to resist changes in its state of motion. Therefore, the toy monkey hung from the roof will also move back due to inertia. So, option a) is likely to happen.

b) A standing person gets pushed back:
Similar to the toy monkey, a standing person will also experience a backward force due to inertia. As the automobile accelerates suddenly, the person's body will try to resist the change in motion, causing them to be pushed back. This is a common experience when a vehicle accelerates quickly. So, option b) is likely to happen.

c) A bag at the roof gets displaced backward:
Again, due to inertia, any object placed on the roof of the automobile will tend to resist the sudden change in motion. As a result, the bag will also be displaced backward. So, option c) is likely to happen.

d) A person in the seat is pushed in front:
This option is different from the others. When an automobile accelerates suddenly, the passengers in the seats are not pushed in the direction of acceleration. Instead, they experience a force pushing them in the opposite direction, which is backward. This is because the seat exerts a forward force on the passengers due to friction. So, the person in the seat is pushed backward, not in front. Therefore, option d) does not happen.

Conclusion:
Based on the analysis, the correct answer is option d) - a person in the seat is not pushed in front but pushed backward when an automobile accelerates suddenly.
