The air resistance is c v 2 or c v like normal. We will use this fact to determine the correct option regarding the horizontal motion. Real projectiles launched on earth experience air resistance. We know that if the air resistance is neglected in the projectile motion, the horizontal component of the force acting on the projectile at any given time will be zero, which means that $$ as the velocity in horizontal direction. ![]() At low speeds, for objects with a high ratio of weight to surface area (like, not a feather or a sheet of paper), we can ignore air resistance. At high speeds, even an aerodynamic bullet experiences a lot of air resistance. With zero air drag force, the analytic solution is well known. This means that if the derivative of horizontal velocity is zero, then the horizontal velocity does not change with time which means it is constant.Thus, in the projectile motion, if air resistance is ignored, the horizontal motion is at constant velocity. The trajectory of the projectile is a parabola. In situations of practical interest, such as. ![]() ![]() Note:Here, we have seen about the horizontal component of velocity. So the horizontal velocity would be vhorizontalinitial - 1/2CdArhov2/mt and the vertical velocity would be (g - 1/2CdArhov2)t.3 answers 3 votes: Q: What formula is used to calculate projectile trajectory with air resistanceA: Best not. But if we consider the vertical component of velocity, in the projectile motion, according to the laws of motion, it is dependent on gravitational acceleration as the projectile experiences the gravitational force vertically and time.
