Newton's second law states that force applied is directly proportional to the rate of change of momentum and is in the direction of application of force.
F is directly proportional to me and a
So f=kma
When f=m=a=1
k=1
So f=may
From newton's first law
A body moving in rest continues to be in rest and in emotion control tinges to be in motion until any external all force is applied on it.
So f is 0
If f is zero either mass or acceleration is 0 too.
Since mass cannot be 0 acceleration is 0
Acceleration is equal to (v-u)/t
So (v-u)/t=0
So (v-u) is 0
So v=u
Thus initial velocity is equal to final velocity.
Hencephalitis a body in rest continues to be in rest and a body in motion continues to be in motion.
