    Calculating Impact Energy: 1km Asteroid at 20km/s = X Megatons of TNT

    Wait is this it? (4/3) * pi * radius^3

    Calculating Impact Energy: 1km Asteroid at 20km/s = X Megatons of TNT

    I am? I'm sorry I have not taken a science class in over 6 years, I am a single mom returning to college so all of this is way over my head.

    Calculating Impact Energy: 1km Asteroid at 20km/s = X Megatons of TNT

    OK so even if I get the approx density, I need the volume as well to calculate mass right?

    Calculating Impact Energy: 1km Asteroid at 20km/s = X Megatons of TNT

    1. An asteroid of 1.0 km diameter will make a crater of about 10 km diameter. How much kinetic energy does the asteroid have if it strikes the surface at about 20km/s. Convert answers to megatons of TNT; 1 megaton = 4 X 10^15 Joules. 2. I do not understand how there is enough...
