An automobile accident cause both the driver and the passenger front airbag to deploy

A. If the vehicle traveled at the speed of 88.6 km/have is now at rest find the change in momentum for both the 68.4 my adult driver and the 34.2 kg child passenger.

B. The adult took 0.564 s and the child took 0.260 s to come to rest. Find the force that the airbag exerted on each individual. Explain why airbags tend to be dangerous to children.

Bianca Perry · Answer 1

A) change in momentum for adult = mv = 68.4 x 88.6 = 6060 kgm/s

change in momentum for the child = 34.2 x 88.6 = 3030 kgm/s

b) force = change in momentum / time

force on adult = 6060/0.564 = 10745 N

force on child = 3030/0.260 = 11653 N
