ANALYTICAL AND NUMERICAL SOLUTION OF THE PROBLEM 
OF METEOROID MOTION IN TERRESTRIAL ATMOSPHERE

UDC 523.68

A system of equations describing meteoroid motion in the terrestrial 
atmosphere is considered. It is shown that the system can be reduced 
to  a  single  second-order  differential  equation  for  the height 
dependence  of  the  mass.  Approximate  analytical  expressions for 
the  solution  of the Cauchy problem for this equation are obtained, 
and  conditions  of applicability of these solutions are determined. 
The  general case  of  the problem is solved numerically. Results of 
mathematical modeling are presented.
