Light-rail systems have been tried all over the country, and they've failed. Although the people who support them have noble int
entions, sadly, the system the city proposes is doomed to fail as well. People simply enjoy their cars too much to endure any inconvenience for the sake of the environment. And I don't blame them. As the owner of Jake's Used Cars and Trucks, I have seen the joy and freedom car ownership brings people. Americans will never abandon that feeling for the sake of being slightly better citizens. I believe it is far more responsible to purchase a high-quality car with good fuel efficiency. Building an entire light-rail system from the ground up, as the city proposes to do, will be more wasteful in the end if nobody uses it — not to mention that it will take years to build and cost taxpayers millions of dollars. I encourage all city residents to vote against the light-rail system on May 1. Which statement best describes the author's point of view? A. The author thinks Americans should be more environmentally responsible. B. The author wants citizens to visit his car dealership. C. The author is opposed to the light-rail project. D. The author would like the city to implement its project successfully.
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.
Now Velocity and speed have the same magnitude. Velocity being a vector quantity has a definite direction. Whereas speed is a scalar quantity,it indicates only the magnitude an doesn't define any direction.
Find the horizontal components vcos30 ...one goes right and one goes left so they cancel each other. Find vertical components vsin30.....there are two of them.... so 2vcos30....hey presto... resultant velocity = 2vCos30
