Question

A body is thrown horizontally with velocity $\sqrt{2gh}$ from the top of a tower of height h. It strikes the level ground through the foot of tower at a distance x from the tower. The value of x is

• A. h
• B. $\frac{h}{2}$
• C. 2 h
• D. $\frac{2h}{3}$

Answer 1

Answer: (C)

2 h

Answer 2

$x = u \times \sqrt{\frac{2h}{g}} = \sqrt{2gh} \times \sqrt{\frac{2h}{g}}$

∴ $x = 2h$
