"We Don't Do Homework"

Heaven help the student who actually does come to this site asking people to do his homework. Dopers delight in posting so much bullshit that any student who used it would get an “F,” plus having the paper circulated among the teachers for laughs.

And we don’t believe in Heaven, so s/he’s screwed.

I have a question:

If a train leaves the station at 1 pm and travels at a rate of 72 mph. Another train leaves the same station an hour later and travels at rate of 90 mph. The second train follows the same route as the first, on a track parallel to the first. How long will it take the second train to catch up to the first?

It will never catch up, as by the time it gets halfway the other train will have moved on, and by the time it gets halfway from where it is to where the other train has moved on to, the first train will have moved on again, and so on and so on. Therefore the second train will never catch up. QED

But if you fire a laser from the second train, it would exceed the speed of light, proving that relativity is a lie, and incidentally, blasting the first train before it even left the station.

And THAT’S how they built the pyramids!

It was a bitchy set of first responses, which was why I posted what little i could, even though I’m not educated at all on that late in Japanese history (or any of it, but I’m a little better at medieval Japan) - I thought some positive response could offset the dickishness, even if it was a reddit link

Assuming two straight lines, constant rates of speed, no changes in time zone, gravitational pull, or wind resistance, and that the trains only pass spherical cows…4 hours.

Are the trains on a treadmill?

No, but if you want, you can switch to track number three.

Edit: also, usedtobe’s response was asshole, and I liked the wassup bitches counter.

Now that we have that settled, I too have a question that is purely of personal interest and is definitely not a homework question:

A rectangular box has no top and two intersecting partitions.
A. Write a function of three variables for the number of cubic units in the volume of the box.
B. Write a function of three variables for the number of square units of material needed to construct the box.

Please show all your work in your answer. Thank you in advance.

Find the building super and say “If you tell me the height of this building, I will give you this swell barometer.”

Your homework assignment is to link to the thread in question.

Well, so much for all that iggorance-fighting that we pretend to do around here.

Even assuming all that, you’ll still have a problem with quantum randomness.

From the title, I was vaguely hoping this thread would contain anecdotes about spoiled-brat overly-entitled kids with helicopter parents who refuse the instructions of teachers.

Those really angry up the blood.

I never did my homework, and that’s why I had to go back to college later in life to get some actual qualifications.

Hey, no one around here is fighting Igors!

You’re correct. If one of the trains isn’t being observed, it’s possible that the train is travelling in both a straight line and a wave simultaneously.

In addition, since we know the speeds of both trains, it is impossible to determine their location or direction.

I amend my answer. There isn’t a known solution.

A. Volume equals width x height x depth
V = whd

B. Assuming the width and depth are the dimensions that are partitioned,
front side = back side = middle pane = width x height
left side = right side = center pane = depth x height
Area equals (front side + back side + middle pane) + (left side + right side + center pane) + bottom side
A = 3wh + 3dh + wd

Thanks! I kept wondering about that.

So this is Schrödinger’s train? And it may or may not run over the cat that may or may not be in a box on the tracks?
