PASSAGE
A projectile is launched from the origin with initial speed v0v_0 at angle θ\theta above the horizontal. Neglect air resistance. Consider the position vector r(t)\mathbf{r}(t), velocity vector v(t)\mathbf{v}(t), and acceleration vector a\mathbf{a} (constant) during flight.
At the instant of maximum height, which of the following statements about the vectors r\mathbf{r}, v\mathbf{v}, and a\mathbf{a} is necessarily true for all valid launch angles 0<θ<90°0 < \theta < 90°?
