The velocity distribution of molecules in a beam coming
out of a hole in a vessel is described by the function F (v)= A V3e-mv2/2117',
where T is the temperature of the gas in the vessel. Find the most
probable values of
(a) the velocity of the molecules in the beam; compare the result
obtained with the most probable velocity of the molecules in the
vessel;
(b) the kinetic energy of the molecules in the beam.
