A 75.0 kg 0erson is riding in a car moving at 20.0 m/s when the car runs into a pillar. The person hits the car's airbag, which compresses over 0.015 s. The person comes to rest.

A) what is the magnitude of the momentum of the person riding in the car before the collision?

B) What is the average force (magnitude and directions) on the person in the car from the airbag during the collision? Assume that the car was moving in the positive x directions.
