Question

Which statements are true?

a) Personnel whose attention is diverted from traffic
b) Traffic flow is moving +25 mph

Answer 1

The correct answer is none of the above since the car is moving at a constant speed in a single direction, meaning it is not accelerating.

Step-by-step explanation:

Let's address each part of the statement in relation to a car moving at a constant speed on a straight road:

• a person standing up from a seated position - This describes a change in velocity (speed and/or direction), therefore it involves acceleration.
• a car accelerating while driving - This directly implies a change in speed, which is acceleration. Since the car in question is moving at a constant speed, it is not accelerating.
• both of the above - Neither situations apply to a car moving at a constant speed in a single direction, so this option is incorrect as well.
• none of the above - This is the correct choice. Both other options involve acceleration, which is not occurring in a car moving at a constant speed.
