Best Answer: Ignoring air-resistance, the horizintal distance covered by an object projected with a velocity, v, and at an angle of Î¸ from the horizontals is: s = vÂ²sin(2Î¸)/g Assuming constant velocity and gravitational force, s is maximised when sin(2Î¸) is maximised.est Answer: Ignoring air-resistance, the horizintal distance covered by an object projected with a velocity, v, and at an angle of Î¸ from the horizontals is: s = vÂ²sin(2Î¸)/g Assuming constant velocity and gravitational force, s is maximised when sin(2Î¸) is maximised.
