Question

how to find initial velocity without final velocity

Answer 1

s = ut + (1/2)at² .
where,
s:displacement
u:initial velocity
a:accleration
t:time

Answer 2

There are some eqation's of motion :

• The first equation of motion is :

$\star \boxed{ \sf \red{v = u + at}}$

1. u stands for Initial Velocity
2. v stands for Final Velocity
3. a stands for Acceleration
4. t stands for Time

• The second equation of motion is :

$\star \boxed{ \sf \red{s = ut + \frac{1}{2} \times {at}^{2} }}$

1. s stands for Distance
2. u stands for Initial velocity
3. a stands for Acceleration
4. t stands for Time

• The third equation of motion is :

$\star \boxed{ \sf \red{ {v}^{2} = {u}^{2} + 2as}}$

1. v stands for Final velocity
2. u stands for Initial velocity
3. a stands for Acceleration
4. s stands for Distance

So,we can calculate initial velocity without final velocity by using second equation of motion.
