On the minimum velocity of a projectile in a linear resisting medium

Abstract

A projectile moving in linear resisting medium was considered in this study. A projectile experiencing a drag force will eventually move with terminal velocity as the limiting value. This study discusses a minimum velocity that is less than the terminal velocity. This paper also describes some characteristics of the minimum velocity especially the coordinates in the trajectory where the object moves with minimal speed. Numerical calculations were employed to solve some derived equations. Some graphical user interfaces were used to present the results.
