Use the following information to answer the next question
In an air bag safety test, two identical crash test dummies are placed in a vehicle equipped with air
bags. The air bag in front of one of the dummies is disabled so that it does not function. The car is
then crashed into a rigid barrier and sensors within each of the dummies record the forces acting on
the dummies during the collision. A graph of the collision force on the dummies as a function of time
is shown below

Explanation / Answer
1) disabled as the maximum force on dummy 1 is attained ina very short time
2) impulse experienced by dummy 1 is larger than the impulseexperienced by dummy 2 as impulse = force *time
and the magnitude of foerce is larger for dummy 1 than dummy 2
