Question

A meteroid with a mass of 797 metric tons (1 ton=1000 kg) slams into the Earth at a speed of 31km/s. How much energy must the Earth absorb?

Answer 1

This IS NOT as ASTROLOGY question.  Perhaps you meant to say ASTRONOMY?

 

The earth would absorb the kinetic energy of the meteoroid, which is

 

K = mv²/2 = [797(1000 kg)] (31,000 m/s)² / 2 = ? joules
