Two girls each weight 500 N. Ride in a car traveling at 20.0 m/s. One wears a seat belt. The other does not. In an accident the girl wearing the seat belt is brought to a stop in 0.120 seconds. The dashboard brings the other one to a stop in only 0.00800 seconds.

What is the impulse exerted on each girl?
