car
SUV
the car and the SUV have the same momentum
none of the above
A 2,000-kilogram SUV collides with a solid bridge pillar with a mass of 150,000 kilograms. Which statement regarding the collision is correct?
the bridge pillar and SUV experience the same size of force
the bridge pillar and SUV experience the same acceleration

The use of seat belts and air bags save lives during vehicle crashes because they:
decrease the crash duration.
increase the crash duration.
increase the forces on the vehicle’s occupants.
increase the acceleration experienced by the vehicle’s occupants.
Assuming all have the same stiffness, which crush zone on a vehicle would provide the greatest protection to occupants during a collision?
short
medium
long
all three would provide about equal protection
All other factors being equal, as the speed of a collision increases, the injuries to a vehicle’s occupants typically:
decreases.
increases.
is not affected.
none of the above
For a given crush zone length, which crush zone stiffness would result in the smallest body acceleration of a vehicle occupant for a given collision?
soft
medium
stiff
all three would produce about the same body acceleration
A given vehicle has the same stiffness of the crush zone. Which crush zone length would result in the longest crash duration?
short
medium
long
all three would have about the same crash duration
The crush zone of a vehicle is designed to:
absorb energy and decrease crash duration.
increase acceleration and decrease crash duration.
absorb energy and increase crash duration.
decrease acceleration and decrease crash duration.
