Query: Wave function of classical particle in linear potential   The problem of classical particle in linear potential is studied by using the
formalism of Hilbert space and tomographic probability distribution. The
Liouville equation for this problem is solved by finding the density matrix
satisfying von Newmann-like equation in the form of product of wave functions.
The relation to quantum mechanics is discussed.
