A grindstone of mass 12 kg and radius 0.3 m is initially rotating freely at 48 rad/sec. An axe is brought into contact with the
grindstone, which brings it to a stop in 6.6 seconds. Assume the grindstone is a uniform solid cylinder. 1) What is the moment of inertia of the grindstone around its rotation axis
Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny supersymmetric strings.
