Final answer:
It is false that you cannot steer if your engine dies; steering just becomes harder without power assistance. On a straight road with a constant speed, the car is in uniform motion.
Step-by-step explanation:
In response to the question: In the event your engine dies, it is false that it is impossible to turn the steering wheel. Instead, what happens is that when the engine dies, the power steering pump is no longer operated by the engine, which makes the steering wheel significantly harder to turn. However, you can still steer the vehicle, albeit with more effort. In a situation where a car is moving on a straight road at a constant speed in a single direction, the vehicle is exhibiting uniform motion, which means the speed and direction are consistent over time, and there is no acceleration or deceleration.
