What will be the ratio of the distances traveled by a freely falling body from rest in 4th and 5th second of its journey?

Let us use Sn = u + 1/2 a [2n-1]
For n = 4, S4 = 0 + 1/2 g . 7 = 7/2 g
For n = 5, S5 = 0 + 1/2 g . 9 = 9/2 g
So required ratio S4/S5 = 7/9

The sumof the kinetic and potential energies of a freely falling body is?
If the body is freely falling, this sum will remain constant.
Does an object that is freely falling have mass?
Yes, mass is an intrinsic property of matter. However a freely falling object will experience no weight.
What changes in a freely falling body?
Velocity
How equation of motion are modified for freely falling objects?
The equation of motion is not modified. Net force = mass x acceleration, whether freely falling or not.
What is a freely falling projectile?
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
What can be said about the distance that a freely falling object travels in one second?
With the information given, all that can be said is that the distance is greater than the distance the object traveled in the previous second.

What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Where does the law of gravity operate?
Freely falling bodies
What is a freely falling projectile?
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
What are the factors affecting freely falling bodies?
force and gravity
When a body is falling freely which force act on it?
no force act on it
What is constant for an object falling freely towards the earth?
No characteristics of a falling body appear on the list provided with the question.
What is the direction of the acceleration of a freely falling body?
9.8 m/s2
