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?

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

Having the potential and kinetic energy in place

Mathematically  solving for Average force

Therefore Average force is given by

its c i just checked it

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
