A classic problem of the motion of a projectile thrown at an angle to thehorizon is studied. Air resistance force is taken into account with the use ofthe quadratic resistance law. The projectile motion is described analyticallywith fairly simple formulas. They make it possible to calculate basic motioncharacteristics and trajectory as easily as in the case of a parabolic motion.There is no need to study the problem numerically. The proposed formulas areuniversal, that is, they can be used for any initial conditions of throwing. Inaddition, they have acceptable accuracy over a wide range change of parameters.The motion of a baseball, a tennis ball and shuttlecock of badminton arepresented as examples.
