Question

A ball falls freely under gravity the distance covered in first, second, third second of the motion are in the ratio

Answer 1

Explanation:

The ratio of "first , second, and third motion is in the ratio of

Solution:

According to the given question here we need to find the ration of body at time t = 1s, t = 2s and t = 3 s.

According to Newton’s equation of motion,

we are having  that,

Where “s” is the distance travelled by body , “u” is the initial speed and  “a” is the acceleration .

Here the body is falling freely due to gravity, so the acceleration will be that due to gravity.

a = g and the initial speed of the body will be 0.

For distance travelled in t = 1s  

For distance travelled in t = 2s

For distance travelled in t = 3s.

The ratio of the distance travelled in t = 1s , t= 2s and t = 3s is
