Journal of Advances in Physics, 2016. Vol. 11, No. 5. A classic problem of the motion of a projectile thrown at an angle to the horizon is studied.

Simple analytical formulae are used for constructing the envelope of the family of the projectile...
Pyrotechnica, 1992. XIV. — P. 203-215. If one has a reasonably accurate computer model, it is usually appropriate (cheaper and faster) to rely primarily on modeled results, supplemented with limited experimental results. The case of aerial shell ballistics is no exception. The mathematical basis for such a ballistics model is derived, and the simplifications and assumptions of the...
Arch. Appl. Mech. 2013. 85(4). — P. 395-414. The paper is devoted to the motion of a body in a fluid under the influence of gravity and drag. Depending on the regime considered, the drag force can exhibit a linear, quadratic or even more general dependence on the velocity of the body relative to the fluid. The case of quadratic drag is substantially more complex than the linear...
J. Service Science & Management, 2010, 3. P. 98-105 We study projectile motion with air resistance quadratic in speed. We consider three regimes of approximation: low-angle trajectory where the horizontal velocity, u, is assumed to be much larger than the vertical velocity w; high-angle trajectory where w u ; and split-angle trajectory where w u . Closed form solutions for the...
American Journal of Physics, 1977. Vol. 45, No. 7. We consider two-dimensional motion of a projectile experiencing a constant gravitational force and a fluid drag force which is quadratic in the projectile's speed. The equations of motions are coupled nonlinear equations. Their solutions have general properties which are easily visualized, although much different from those...
Physics Education 2009, 44 (4) An educational and historical study of the projectile motion with drag forces dependent on speed shows, by simple results, that trajectories quite similar to those depicted before the Galilean era may be obtained with a realistic choice of quantities involved. Numerical simulations of the trajectory in space and velocity coordinates help us to...
