Torricelli's TheoremHardQuestion 6459
Question
Tank (H=2 m full) with hole at depth h=1 m from top. Horizontal range on ground (floor at base of tank):
- A2 mCorrect
- B√2 m
- C√5 m
- D√3 m
Correct answer
2 m
Explanation
v = √(2gh) = √(2×10×1) = √20. Height to fall = H−h = 1 m. t = √(2×1/10) = √0.2. Range = v×t = √20×√0.2 = √4 = 2 m.
