GotLag posted:IMO the Japanese response was even worse than the god-awful retarded repair job. The US base at Yokota had the plane on radar, had a helicopter at the crash site within 20 minutes, and rescue teams ready to deploy... and then someone in the Japanese government told them to stand down. The Japanese responders didn't even try to reach the site until the next day, they spent the first night pitching tents in a village 60 km away. Meanwhile a whole bunch of people who survived the initial crash are bleeding and/or freezing to death, with only four survivors by the time Japanese rescuers actually arrived.

Flight time of 16 seconds -> 8 seconds to highest point -> d = 1/2at^2 -> 313.6 meters

This is Japan.txt, the new Godzilla movie was a pretty good critique of the absurd bureaucracy of the Japanese government. Film Critic Ollie Barder posted:In many ways, this new movie is a searing indictment of how the 2011 Tohoku earthquake and tsunami as well as the Fukushima disaster were mishandled by the Japanese administration. In that, the old guard with their overly complex and corpulent bureaucratic ways were simply unable to deal with a crisis in any kind of efficient or fluid way. This is shown repeatedly in [Shin Godzilla], as the high-ranking members of the cabinet, comfortable in their positions of power, use the hierarchical nature of the system they reside within to protect their own positions, at the expense of the lives of their citizens.

Phanatic posted:There's now security camera footage of the boiler being set free: Here at our office earlier this week, we had a training school for boiler techs, so you can bet that this whole thing was a hot topic for everyone. Our best guesses were: 1) the burner kept firing on a steam boiler without water, and then water was added, flashing to steam or 2) there was mud buildup inside, holding a fair amount of water that all suddenly flashed in a similar manner. We all knew immediately that it wasn't a natural gas explosion because it was too energetic and came from the bottom of the boiler. Either way, regular maintenance would have avoided this. I'm just glad my company wasn't the one providing the burner, so we're in the clear.

Collateral Damage posted:Will an object launched into the air at a given speed always come back down at the same speed, assuming its ballistic coefficient doesn't change? No, an object will have a terminal velocity based on its aerodynamics which can be significantly lower than its initial speed.

Collateral Damage posted:Will an object launched into the air at a given speed always come back down at the same speed, assuming its ballistic coefficient doesn't change? Aside from air resistance, pretty much. The object is on a ballistic trajectory, and under a constant acceleration due to gravity from the moment the launching force ceases to act on it. E: poo poo, forgot about terminal velocity, which comes AFAIK from the air resistance that I just handwaved away.

rotation, center of gravity and whether or not its changing shape in the air based on explody bits also matters.  physics is cool.

The most elegant proof of this is that gravity can’t give you free energy, so when a launched object returns to its original altitude, it must have the same kinetic energy (and therefore speed) as when it left.

Platystemon posted:Yes. Right, this is why bullets fall back to earth at super sonic speeds. "Bullets fired into the air usually fall back with terminal velocities much lower than their muzzle velocity when they leave the barrel of a firearm. Nevertheless, people can be injured, sometimes fatally, when bullets discharged into the air fall back down to the ground. Bullets fired at angles less than vertical are more dangerous, as the bullet maintains its angular ballistic trajectory, is far less likely to engage in tumbling motion, and so travels at speeds much higher than a bullet in free fall."

Ignoring air resistance is a good way to get a ceiling to consider, all that's left is to check the fraction of terminal velocity it is at the high velocity parts to say how confident you are or do some handwaving to estimate what a ceiling would be if it was faster at initiation. They should probably just stop teaching ballistics in college physics because when discussing on the internet no one seems to remember to check what fraction of terminal velocity its spitting out of the equation at the most kinetic points.

There's also the fact that it has to accelerate to terminal velocity but let's get back to gifs/pics of poo poo being hosed up both safely and unsafely.
