    An object is projected at an acute angle of θ\theta below the horizontal, with an initial speed of 30 m s−1^{-1} from a position 90 m above ground level. The object hits the ground 90 m horizontally from its projection point. Use vector calculus to determine θ\theta in its simplest form. Assume that the magnitude of mean acceleration due to gravity on Eart…
