Asteroid

I want to paint my car at Earl Scheib, but they dont know what Meteorite Silver look like. Do anybody know the Paintcode to Meteorite Silver so theyll have a better reference?

There is a paint code tag on the inside fender well of your car. If not go to your dealership or paint shop and give the parts counter your vin # . The paint code is usually in the vin#.

(1) An object is fired vertically upward from the Earth with an initial speed that is less than the escape speed. (2) A meteorite falls towards the Earth; at a certain height, the meteorite is at rest with respect to the Earth. Question: how is (2) the "time reversal" of (1)? Why can we use the same equation for both questions by reversing Vf to Vi? Any help will be appreciated. Thank you.

It isn’t. The effects of atmosphere aren’t symmetric. The meteorite is never at rest with respect to earth until it lands. If you could ignore the atmosphere, each is an object with a specific position and velocity, acted on by earth’s gravitational field.

And you can’t answer that question, what is a meteorite’s average initial speed?

The initial average initial speed of meteorites is zero… they are meteors after impact on Earth.

Meteors reach from 13 km per second to 150 km/s, depending on the type of meteoroids. also, it depends on the angle. The time can thus vary from about 2 minutes seconds for a slow shallow meteor to about half a second for steep fast meteors.

I got give a present, which is apparently a small meteorite, its seams to be metal, and magnetic, but how can i know wether its just a fake or a really meteorite?

This meteorite identification page can help you out: http://www.meteoritemarket.com/metid1.htm

You can quickly give a negative answer, if your candidate meteorite does not have a fusion crust (a thin flaky, rusty brown or black surface). That it’s magnetic is a good sign, as 90% of the meteorites found are nickle-iron.

Area of Earth = 5.1 x 10^8 km^2
about 500 meteorites fall every year
area of los angeles = 1200 km^2

estimate the probability tat a meteorite will fall in Los angeles in the next year.

6/(5.1×10^3)

There is nothing that can be done to prevent this from happening and you have 24 hours before the meteorite strikes. What would you do?
The meteorite is the size of a small planet and total annihilation is certain. Nothing can be done to prevent this from happening and you have 24 hours before the meteorite strikes. What would you do?

Statistically speaking, the meteor is probably very small. I’d ignore it, just like I ignore the thousands of other meteors that hit Earth each day.

As for what I’d do on the last day of my life, it’s simple. I would die.
