Explanation Given: The motion of the projectile is y = − g sec 2 θ 2 v 0 2 x 2 + ( tan θ ) x + h . Proof: Neglecting air resistance, the path of a projectile launched from an initial height h with the initial speed v 0 at an angle of elevation θ is described by the vector function, r ( t ) = ( v 0 cos θ ) t i + [ h + ( v 0 sin θ ) t − 1 2 g t 2 ] j …… (1) The rectangular coordinates are, r ( t ) = x i + y j …… (2) Compare equation (1) and (2), x = ( v 0 cos θ )
