The time of flight, range and the angle which maximizes the range of a projectile
in a linear resisting medium are expressed in analytic form in terms of the recently
defined Lambert W function. From the closed-form solutions a number of results
characteristic to the motion of the projectile in a linear resisting medium are
analytically confirmed, and asymptotic and approximate expressions valid within
the weak and strong damping limits are developed. The problem provides an
accessible account of the increasingly applicable Lambert W function and
highlights much of the important mathematics associated with this simple yet
rapidly emerging ‘implicitly’ elementary function.
