Solution 1
The correct answers to the question "Which of these are true about safety belts?" are:
-
Safety belts cause passengers to decelerate: This is true. In the event of a sudden stop or crash, a safety belt will cause the passenger's body to slow down at the same rate as the vehicle, reducing the risk of injury.
-
Safety belts provide a force: This is also true. When a vehicle suddenly stops or crashes, the safety belt provides a force that opposes the forward motion of the passenger, helping to keep them in their seat.
-
Safety belts reduce a passenger's mass: This is false. A safety belt does not change a passenger's mass. It simply restrains their movement to prevent them from being thrown forward in a crash.
-
Safety belts cancel out the force of impact: This is false. Safety belts do not cancel out the force of impact, but they do distribute it over a larger area of the body, reducing the risk of serious injury.
Solution 2
The correct answers to the question "Which of these are true about safety belts?" are:
-
Safety belts cause passengers to decelerate: This is true. In the event of a sudden stop or collision, the safety belt will cause the passenger to decelerate at the same rate as the vehicle, reducing the risk of injury.
-
Safety belts provide a force: This is also true. When a vehicle suddenly stops or crashes, the safety belt provides a backward force on the passenger, preventing them from being thrown forward.
-
Safety belts reduce a passenger's mass: This is false. A safety belt does not change a passenger's mass. It simply restrains their movement in the event of a sudden stop or collision.
-
Safety belts cancel out the force of impact: This is false. Safety belts do not cancel out the force of impact. They distribute the force of the impact more evenly across the body, reducing the risk of injury.
