Answer:
E = 147000 J
Explanation:
Given that,
The mass of meteor, m = 50 kg
The altitude of the meteor, h = 300 m
We need to find the potential energy of the meteor. The formula for the potential energy is given by :

Put all the values,

So, the required potential energy is equal to 147000 J.
Maybe gas? because you can’t see it and it’s formed during a chemical reaction
