Question

About 50,000 years ago, in an area located outside Flagstaff, Arizona, a giant 4.5 107-kg meteor fell and struck Earth, leaving a 180-m-deep hole now known as Barringer crater. If the meteor was traveling at 20,000 m/s upon impact, with what average force did the meteor hit the earth?

Answer 1

`F_A =5.625*10^1^6N`

Step-by-step explanation:

From the question we are told that

50,000 years ago,

A giant 4.5 107-kg meteor

180-m-deep hole

20,000 m/s

Generally for this problem the energy change is given as

`\triangle E=(1)/(2) mv^2 +mgd`

Having the potential and kinetic energy in place

Mathematically solving for Average force
`F_A`

`\triangle E=F_a*d`

`F_A =(1/2* 4.5*10^7(20,000)^2-kg+4.5*10^7*9.81*160)/(160)`

Therefore Average force
`F_A` is given by

`F_A =5.625*10^1^6N`
