A ball is tossed from the top of a building with speed $v_0$ at an angle $\theta$ above the horizontal. Another ball is tossed from the top of the same building with speed $v_0$ at the same angle $\theta$ below the horizontal.

Let $t_1$ and $t_2$ be their times of flight and let $v_1$ and $v_2$ be the velocities of the two balls when they strike the ground.

Which of the following is **TRUE**?
