Problem 15E

Meteor Crater.? About 50,000 years ago, a meteor crashed into the earth near present-day Flagstaff, Arizona. Measurements from 2005 estimate that this meteor had a mass of about 1.4 X 108 kg (around 150,000 tons) and hit the ground at a speed of 12 km/s. (a) How much kinetic energy did this meteor deliver to the ground? (b) How does this energy compare to the energy released by a 1.0-megaton nuclear bomb? (A megaton bomb releases the same amount of energy as a mil-lion tons of TNT, and 1.0 ton of TNT releases 4.184 X 109 J of energy.)

Step-by-Step Solution:

Solution 15E Step 1 of 4: In the given problem, a meteor crashed onto the earth with a mass m=1.4× 10 kg and8 speed v= 12 km/s. Using this given data we need calculate the kinetic energy delivered by meteor to the surface of the earth and we need to compare this with the energy released by a 1.0-megaton nuclear bomb. Given data, 8 Mass of meteor , m= 1.4× 10 kg Velocity , v=12 km/s 3 3 Using 1 km =10 m v=12× 10 m/s To find, Kinetic energy , KE=
