Question

question 6 1 pts based on the previous questions, which of the following statement explains why the airbags can save your life: the airbags reduce the time of interaction of a person with any solid part of a car during a collision, reducing the force exerted on the person. the airbags increase the time of interaction of a person with any solid part of a car during a collision, reducing the force exerted on the person. the airbags reduce the time of interaction of a person with any solid part of a car during a collision, increasing the force exerted on the person. the airbags increase the time of interaction of a person with any solid part of a car during a collision, increasing the force exerted on the person. question 7 1 pts the impulse is directly proportional to the change in the velocity of an object. true false

Explanation:

1. Question 6: According to the impulse - momentum theorem $J = F\Delta t=\Delta p$. Airbags increase the time $\Delta t$ of interaction during a collision. Since the change in momentum $\Delta p$ is fixed in a given collision scenario, increasing $\Delta t$ reduces the force $F$ exerted on the person, which helps in saving lives.
2. Question 7: The impulse $J$ is defined as $J=\Delta p = m\Delta v$, where $m$ is the mass of the object and $\Delta v$ is the change in velocity. So impulse is directly proportional to the change in velocity when mass is constant.

Answer:

Question 6: The airbags increase the time of interaction of a person with any solid part of a car during a collision, reducing the force exerted on the person.
Question 7: True
