Can There Be Two Angles For Same Horizontal Range? Motion in A Plane. Show that there are two angles of projection for which horizontal range is the same. Thus horizontal range is the same for angle of projection θ and α = 90°–θ. How that there are two angles of projection for which the horizontal

Can We Have Same Horizontal Range For Different Angle Of Projection? Can we have same horizontal range for different angle of projection? A projectile can have the same range for two angles of projection. If h1 and h2 are maximum heights when the range in the two cases is R, then the relation between R,h1
