In this one, i'm gonna calc the speed of the shuttle freefalling, as well as gain the kinetic energy solely from the shuttle's weight and speed, not the collision.
In 3:08, the shuttle collided with a satellite. With this in mind, the distance between Earth and the satellite orbital is around 36000 km, or around 36000000 meters.
Timeframe = from 3:08 to 3:29 = 21 seconds.
Speed of the free fall = 1714285.714 m/s.
Now, for the K.E.
The size of a spacecraft is around 2030000 Kg.
K.E. = 2.98286e18 Joules = 713 Megatons of TNT (Mountain Level+)
Collision during a Fight = 713 Megatons of TNT (Mountain Level+)
