An angle of $45^{\circ}$ is the optimal angle when $h=0$
We can find the optimal angle $\theta$ when $h=0$: $\theta = arcsin \left(\sqrt{\frac{v^2}{2v^2+64h}}\right)$ $\theta = arcsin \left(\sqrt{\frac{v^2}{2v^2+(64)(0)}}\right)$ $\theta = arcsin \left(\sqrt{\frac{v^2}{2v^2+0}}\right)$ $\theta = arcsin \left(\sqrt{\frac{1}{2}}\right)$ $\theta = arcsin \left(0.707\right)$ $\theta = 45^{\circ}$ An angle of $45^{\circ}$ is the optimal angle when $h=0$
