Question

question 1 4 pts
an air bag
○ is not a reliable protective device.
○ is an active restraint.
○ must be fastened and adjusted by the occupant.
○ automatically inflates to protect an occupant.

question 2 4 pts
the distance your vehicle travels while you respond to a road hazard is called
○ braking distance.
○ reaction distance.
○ perception distance.
○ stopping distance.

question 3 4 pts
a vehicle going uphill works
○ with centrifugal force.
○ with the force of gravity.
○ against the force of gravity.
○ against centrifugal force.

Explanation:

1. For Question 1: Air bags are passive safety devices that automatically inflate during a collision to protect vehicle occupants, they are reliable, not active restraints, and do not require manual fastening/adjustment by the occupant.
2. For Question 2: Reaction distance is defined as the distance a vehicle travels while the driver responds to a road hazard; braking distance is when brakes are applied, perception distance is while detecting the hazard, and stopping distance is total of reaction + braking distance.
3. For Question 3: Gravity pulls objects downward, so a vehicle moving uphill must work against this downward gravitational force; centrifugal force relates to turning, not uphill travel.

Answer:

1. automatically inflates to protect an occupant.
2. reaction distance.
3. against the force of gravity.
