TheNeedForZ Posted May 3, 2006 Share Posted May 3, 2006 right on...but can a train a mile long accelerate 5 mph in 10 sec? noot likely. wait until you are at a train crossing and the train stops right on the crossing. It takes that train forever to take off again... Ever ride in a fast train? The kind that has a 75mph initial speed? Quote Link to comment Share on other sites More sharing options...
Michael Posted May 4, 2006 Share Posted May 4, 2006 The more important question is, what will this poor train do once it reaches the station in Los Angeles? I mean, that's going to be one harsh arrival! Quote Link to comment Share on other sites More sharing options...
Drftn280zxt Posted May 5, 2006 Share Posted May 5, 2006 22.7492hrs This is correct. Simple physics, but that wording was horrible. With questions like that you just gotta use common sense. I'm in Phys180, which is one of the requirements for my B.S Mechanical Engineering degree, I see problems like this all the time in my homework, and they suck.

mario_82_ZXT Posted May 5, 2006 Share Posted May 5, 2006 >> solve('75*x+(1/2)*5*x^2=3000') ans = -15+5*57^(1/2) -15-5*57^(1/2) >> -15+5*57^(1/2) ans = 22.7492 >> mmmm matlab7 [attach]441[/attach] as you can see' date=' velocity is increasing, otherwise the graph would be one of a straight line.[/quote'] omg i HATE matlab... actually right now I hate engineering in general. school blows, most of my friends get out or have gotten out this/next week. i just took a midterm.....

Drftn280zxt Posted May 5, 2006 Share Posted May 5, 2006 I had one final today, and I've got four more next week, and I am done... till fall anyways then it starts all over again Yaay! Quote Link to comment Share on other sites More sharing options...
olie05 Posted May 5, 2006 Share Posted May 5, 2006 Lol i owned the computing for engineers final yesterday somehow (matlab+fortran77+excel) but i've been getting 50's on the tests. Class averages are in the 40's... yeah... I can appreciate matlab, but I still hate it! Quote Link to comment Share on other sites More sharing options...
