They all looked alike except as to size. They were green with scales, and they had four legs and a long tail.

Answer:
The maximum potential energy of the net, compared to its unstretched potential energy, is:
Explanation:
From the question we are told that
The weight of the man is
The distance of the window to the net is
The distance stretched by net is
Generally from the of conservation energy , the total energy is conserved
This implies that
Where is the initial potential energy of the , man which is mathematically evaluated as
Substituting values
And is the unstretched potential energy of the net
And is the final potential energy of the man which is mathematically evaluated as
Substituting values
The negative show that the direction of the man is against the direction of gravitational pull
And is the maximum potential energy of the net when stretched
So the above equation becomes
So
We would have earthquakes and tsunamis, i think, i don't really know?!?
