Practice Test
Practice Test 1
Ball A is thrown in upward from the top of a tower of height h. At the same time ball B starts to fall from that point. When A comes to the top of the tower, B reaches the ground. Find the time to reach maximum height for $\mathrm{A}$. (A) $\sqrt{(\mathrm{h} / \mathrm{g})}$ (B) $\sqrt{(2 \mathrm{~h} / \mathrm{g})}$ (C) $\sqrt{(h / 2 g)}$ (D) $\sqrt{(4 \mathrm{~h} / \mathrm{g})}$
