About 50,000 years ago, in an area located outside Flagstaff, Arizona, a giant 4.5x10^7 kg meteor fell and struck Earth, leaving a 180 m hole now known as Barrington crater. If the meteor was traveling 20000 m/s upon impact, with what average force did the meteor hit Earth? Help I am not sure how to solve this problem!
F=mg=4.5*10^7kg * 9.8N/kg=4.41*10^8N.
