An asteroid closely passes the Earth at a range of 17200mi and a relative speed of 7.8km/s.The diameter is estimated at 30mwith a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega-tons (M ton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000kgand the explosive energy density of TNT is 4184J/g.Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance.
