Question

2. In February 2013, a meteorite streaked through the sky over Russia. A fragment broke off and fell downwards towards Earth with a speed of 12 000 km/h and struck the ground 10 s later. How far in kilometers did the fragment travel in this time? (3x10 km)​

Answer 1

Explanation:

The Chelyabinsk meteor was a small asteroid — about the size of a six-story building — that broke up over the city of Chelyabinsk, Russia, on Feb. 15, 2013. The blast was stronger than a nuclear explosion, triggering detections from monitoring stations as far away as Antarctica.
