D) all of the above is the answer
<span>v² = u² + 2as </span>
2as = v² - u²
<span>a = (v² - u²) / 2s </span>
<span>a = (20.0² m²/s² - 6.00² m²/s²) / (2 * 50.0 m) </span>
<span>a = (400 m²/s² - 36 m²/s²) / (100 m) </span>
<span>a = (364 m²/s²) / (100 m) </span>
a = 3.64 m/s²
ANSWER: C. The author is opposed to the light-rail project.
EXPLANATION: The author understands the mentality and the sentiments of Americans. He knows the fact very well that people would never compromise their comfort, joy and freedom to become a good citizen. The author thinks they can be rather advised to buy high quality cars with good fuel efficiency than using the light rail system. So, to avoid taxpayers' millions of dollars, he wants the citizens to vote against it.
