Calculation of the time taken by a stone to fall freely through two meters distance


When a stone is allowed to fall freely from rest, it experiences only one force, which is the force of gravity acting downwards. This force causes the stone to accelerate downwards at a constant rate. The acceleration due to gravity is denoted by 'g' and its magnitude is approximately 9.8 m/s².


Calculation of the time taken to fall through one meter distance


The distance travelled by a freely falling stone is given by the formula:


d = ½ gt²


Where d is the distance travelled, g is the acceleration due to gravity and t is the time taken.


When the distance travelled is one meter, the formula becomes:


1 = ½ gt²


Simplifying this equation, we get:


t = √(2/g)


Therefore, the time taken to fall through one meter distance is given by √(2/g).


Calculation of the time taken to fall through two meters distance


Using the formula for distance travelled by a freely falling stone, we can calculate the time taken to fall through two meters distance as follows:


2 = ½ gt²


Simplifying this equation, we get:


t = √(4/g)


Therefore, the time taken to fall through two meters distance is given by √(4/g).


Calculation of the ratio of the time taken to fall through the first and second meter distances


Dividing the time taken to fall through the first meter distance by the time taken to fall through the second meter distance, we get:


√(2/g)/√(4/g)


Simplifying this expression, we get:


√2/2


Therefore, the ratio of the time taken to fall through the first and second meter distances is √2/2.


Conclusion


Thus, we have calculated the time taken by a stone to fall freely through two meters distance and found the ratio of the time taken to fall through the first and second meter distances to be √2/2.
