Question: About 50000 years ago, a meteor crashed into the earth near present-day Flagstaff, Arizona. Recent (2005) measurements estimate that this meteor had a mass of about 1.4×108 kg (around 150000 tons) and hit the ground at 12 km/s.
Part A: How does this energy compare to the energy produced in one day by a standard coal-fired power plant, which generates about 1 billion joules per second?
If possible just a brief explanation how you got the answer?
