Answer 2

Answer:-

The equation for free fall:-

Imagine an object body is falling freely for time t seconds, with final velocity v, from height h, due to gravity g. It will follow the following equations of motion as,

1. h = 1/2gt²
2. v² = 2gh
3. v = gt

Where,

h------------->height traveled

v------------->final velocity

g------------>acceleration due to gravity

t------------->time taken

These equation can be derived from the usual equations of motions as given below, by substituting

Initial velocity u = 0

Distance traveled s = h and

Acceleration a = g

We can see it as follows:

⇒s = ut+1/2at²

⇒v²= u²+2as

⇒v = u+ at

Free fall is the autonomous phenomena of the body with some mass. it only depends on the height from the surface and the time period for which the body is flung.
