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?

Well, everyone knows you're a hateful bitch, so I'm not surprised you'd react the same way.

The rescue is taking place in a mine. My statement was in no way incorrect. *NM*

There is no law that says what has to float your boat and you are a bad person if it doesn't.

It has nothing to do with the fact that it invovles brown people thousands of miles away.
