Can a sharp, diamond bullet going 100mph pierce 200,000 rolls of paper towels

and so would probably break on impact, which means very little penetration.A bullet usually only weighs around 80 grains (a gram is roughly 15.4 grains). It requires a lot more speed (like 10 times what you specify) to cause damage through its momentum. The momentum at 100 mphis very low,......
it is the relative density and mass that counts
there is more to learn about "kinetic energy" which determines how much damage the bullet can do
the mass of 200 thousands rolls of paper ( feathers or air) is much much greater than the bullet

It's a problem of momentum and kinetic energy...
Diamond, although it is hard, is actually quite brittle, and so would probably break on impact, which means very little penetration.
A bullet usually only weighs around 80 grains (a gram is roughly 15.4 grains). It requires a lot more speed (like 10 times what you specify) to cause damage through its momentum. The momentum at 100 mph is very low, and probably would lose most of its momentum puncturing a single sheet of paper towel, never mind a roll.

Depends entirely on the sectional density of the bullet. If the bullet has a diameter of a millimeter or two but many kilometers long, weighing many thousands of kilos, it would probably have sufficient energy and a large enough sectional density to penetrate all the paper towels you could possibly line up.
