Question

State whether true or false.
The time taken by a body which is falling freely from a height h to reach the ground is equal to $\sqrt{\frac{2h}{g}}$

• A. True
• B. False

Answer 1

The correct option is A True

Initial velocity of the body $u=0$

Acceleration $a=g$

Using $S=ut+\frac{1}{2}a{t}^2$

Or $h=0+\frac{1}{2}g{t}^2$

$⟹t=\sqrt{\frac{2h}{g}}$

So the given statement is true.
