PIZZAQ! Before the Flying Saucer destroyed the Washington Monument and almost smooshed Little Bobby to peanut butter, how long does it take a besbol dropped from the top to hit the ground?

Click to enlarge. Flee for your life.

I was born and grew up in Washington DC USA. One summer day I visited the Washington Monument. Suddenly with no warning an evil, hostile Flying Saucer from Outer Space smashed into the Monument, and toppled it over. Dozens of tourists were smooshed to peanut butter; I barely escaped with my life. Other Saucers destroyed the U.S. Capitol.

This really happened; it's not Fake News. Anyone who says these images are really from the movie "Earth vs. the Flying Saucers" is probably a teenager in Macedonia with a laptop. In other news from Macedonian laptops, the USA Democratic Party is keeping children as sex slaves in a popular pizza restaurant in Washington DC.

Notice the height of the Monument. Every DC kid had to memorize this height for trig and physics class. PIZZAQ! If you drop a besbol from the top of the Washington Monument, how long does it take for the besbol to hit the ground? (Naturally you do this experiment in a vacuum.) (4 slices Chicago-style pizza with extra mozarella.)

Now....the Washington Monument has a height of 555 feet or about 169 meters. Since your vleeptronness wants us to conduct this experiment in a vacuum we are talking about free fall (no gravity) and I don't need calculus which is a good thing because we never had that in school. Please don't be shocked, we also never heard about Evolution, history after 1918, world literature or classical music. Now then....lemme see....

oh no, it's all about ordinary Earth gravity, that's what the equation is based on. But the vacuum part -- the atmosphere (wind resistance, that sort of thing) would affect the rate at which a massive object falls a specific distance to the ground. So you pretend you're dropping the besbol from the top of the monument in a vacuum.

Galileo (I think from the top of the Tower of Pisa) proved that (again, in a vacuum) a brick and and a feather take the same amount of time to hit the ground. Aristotle had said bricks fall faster than feathers. I love it when Aristotle was Wrong, which was often.

Oh I think one of the Apollo moon landings, an astronaut demonstrated Galileo's experiment that the descent rate of objects of unequal masses is independent of the mass of the objects, they both hit the ground at the same instant. (No atmosphere on the Moon.)

nota bene the video from the moon with the hammer and the feather is in my first post. Will we ever see someone walking on the moon (or Mars) in our lifetimes ?

As all Yerpeens (except UKers) know, distance is measured in the metric system. But the USA still clings proudly to feet, miles, inches. Things got busy here -- I'm about to hook up my NEW COMPUTER (with AMD chip!!!), but for the benefit of you Yerpeens, I'll take this step by step. You were right -- in metric, the height of the Washington Monument is

169.2942 meters

btw UKers stick with feet etc. which originally was the size of the king or queen's foot -- so it changed every time a king or queen got his or her head chopped off. Napoleon said screw that, and the meter was defined as a fraction of the circumference of the Earth (which they measured incorrectly at the time).

In "1984," Winston Smith hated the government's new metric volumes for beer & ale bottles. He hated going to a pub and ordering 0.5682612 liters of beer. It just wasn't British.
