Question

Scientists discover an asteroid that is moving through space. what information is need to determine the average speed of the asteroid?

A the mass and size of the asteroid

B the distance the asteroid is from earth

C the direction the asteroid is moving and distance from earth

D how far the asteroid has moved in 24 hours

Answer 1

Step-by-step explanation:

This is equal to the impact energy. For example, consider an asteroid that is one kilometer in diameter and weighs 1.4 billion tonnes (M = 1.4×1012 kilograms), and is traveling at 20 kilometers per second (V = 20,000 m/s). The kinetic energy would be equal to (1/2)×1.4×1012×(20,000)2 = 2.8×1020 Joulesp
