Answer 2

Question :-

• When initial velocity becomes greater than final velocity what happens to the acceleration of the body ?

Answer :-

• If the initial velocity becomes greater than final velocity then the acceleration will be negative.

Explanation :-

We know that

$\sf{\boxed{\boxed{a = \dfrac{v-u}{t}}}}$

Here,

a = Acceleration

v = Final Velocity

u = Initial Velocity

t = Time

If u > v :-

Acceleration will be negative if the initial velocity is greater than final Velocity.

Example :-

Let ,

u = 20 m/s

v = 10 m/s

t = 2 m/s

$\implies\sf{a=\ \dfrac{v-u}{t}}$

$\implies\sf{a = \ \dfrac{10-20}{2}}$

$\implies\sf{a = \dfrac{-10}{2}}$

$\implies\sf{a =\ -5 }$

So, we can say that if the initial velocity becomes greater than final velocity then acceleration will be negative.
