Imagine that you have to pull up a miner of 76kg from a hole 700 metres deep. How much work will you have to do? 1 point (pass value)

Approx 53.2 kJ. Or I guess 53 kJ for sig figs.
removing rock in a circle with a diameter of 60 cm for 700 metres will lead to what amount of work? (This one is probably two points, for pass with distinction, since it involves more complicated processes)

Oh, hmm. I assume it involves some integration. Or just calculating the volume of the rock removed, which would be approx 198 cubic metres. Hmm, no, I think you probably have to integrate the potential energy function from 0 to 700 m for that. Unfortunately, I don't know how to do this anymore (if I ever really did)
How long will it take for the miner who had both his wife and his mistress waiting for him to ask to be put back down into the hole (No points, but an opportunity to show excellence)

lol. I'll bet he goes back to 'work' asap
and one for pol/economic sci: What is a life worth? We're not willing to spend more than 100,000 per possibility of saved lives to build enough hospitals to keep people from dying. However, digging up miners cost a whole lot (I don't know how much), is it worth it due to political capital?

Obviously, and think about how much money the global media made off of it. It's definitely a positive externality.

Is it awful of me that I don't really give a crap about this mine rescue business? - 14/10/2010 12:58:18 AM 1703 Views
I feel the same way. - 14/10/2010 01:03:51 AM 1035 Views
They're rescuing mines? - 14/10/2010 01:23:05 AM 1146 Views
The rescue is taking place in a mine. My statement was in no way incorrect. *NM* - 14/10/2010 01:24:05 AM 562 Views

I don't believe they've gotten a heart to work yet. - 14/10/2010 10:22:18 PM 931 Views

This one could've gone either way. - 14/10/2010 11:22:13 AM 1113 Views

Lucky you. Given that you described it as "managed to avoid" the story, you're totally HBC material. *NM* - 14/10/2010 04:27:04 PM 587 Views
Is there a button for my shirt? - 14/10/2010 10:18:27 PM 990 Views
Why? Is your neckline plunging too low? *NM* - 14/10/2010 10:24:13 PM 590 Views

I mainly watch for the weather. At least they didn't fuck with that. *NM* - 14/10/2010 08:36:17 PM 548 Views
Probably because it's tough to stick your dick in a cloud. *NM* - 14/10/2010 09:54:20 PM 575 Views
