A2-kg stone falls 100 meters near the surface of the earth. it strikes the ground without any rebound thereby making a completely inelastic collision with the earth. approximately how much kinetic energy is transferred to the earth in this process?

Explanation:

When a stone of mass 2 kg falls from initial height H = 100 m then its total potential energy will convert into kinetic energy just before it will hit the ground

So we will say

so we will have

now we know that when collision is completely inelastic collision then the mechanical energy is completely lost in the form of thermal energy and other forms of energy

so here total kinetic energy is transferred to the Earth

so we have

less than one you can't create energy
