An object who’s mass is 100 kg and who’s elevation is 100 m
has 10^5 J of potential energy with respect to the street level.
For the obvious reason the kinetic energy of that object must
not be excessive at the bottom. Therefore roughly 2*10^4
calories of THENA must appear in the process. Where does
it appear? Partly in the sliding object, partly in the canvas and
a tiny fraction in the air.
