Unformatted text preview: Therefore, all the equations derived in the previous section are valid once the scalarvalued functions are turned into vectorvalued ones. As an example, consider the position function x (t) = a t 2 + v t + x , where a = (0, 0,  g) , v = (v x , 0, v z ) , and x = (0, 0, h) . The above vector equation for position can be broken down into three onedimensional equations: x(t) = v x t, y(t) = 0, z(t) =  gt 2 + v z t + h...
