Question

The final velocity of the freely following body when it reaches the ground in t seconds

Answer 1

Answer:

We have average velocity =

2

g

Since it is a free fall, average velocity, v=

t

S

=

t

2

1

gt

2

=

2

g

, where t is the time of descent and initial velocity is zero.

We know that for a free fall, velocity with which it reaches the ground: V=gt, where t is time of descent .

Substituting the same in the above equation for average velocity:

2

V

=

2

g

∴V=g
