Range (horizontal distance) to the projectile Is given by a study conducted by Travel = U ². sin2α / g and where the research Range, m U = initial velocity, l / α = angle of launch = 9.8 l / s or more Connect the value of ², we 2 = [6.8 ² / 9.8] * sin2α or GET due to gravity The G = acceleration or horizontal sin2α = 2 * 9.8 / 6.8 ² = 0.4239 2α = arcsin (0.4239) = 25 °, or α = 12.5 ° ANS: ------ launch angle = 12.5 ° in the horizontal and the top
