Question 2 • [HSPHY] Physics Sem 1 (26-27)

How does an airbag help protect a passenger in a car following a car accident?

Answer
A
It shortens the passenger’s stopping time, and this decreases the force.
B
It shortens the passenger’s stopping time, and this increases the force.
C
It increases the passenger’s stopping time, and this decreases the force.
D
It increases the passenger’s stopping time, and this increases the force.

Explanation

An airbag makes the passenger take longer to come to a stop by cushioning the impact. For the same change in momentum, increasing the stopping time decreases the force on the passenger. Therefore, the correct choice is “It increases the passenger’s stopping time, and this decreases the force.”
