"Retardation means negative acceleration. This happens every time when the velocity of an object decreases.

So obviously we can say that when final velocity is less than initial velocity; we are going to have negative acceleration.

So formula will be the same as that of acceleration.

As acceleration can be defined as the rate of change of velocity i.e. mathematically: a= (v-u)/t

Where v = final velocity, u= initial velocity & t= time taken to change the velocities.

So in case of v<u; you are going to get a negative value of acceleration which is also called retardation/de-acceleration/deceleration.

Answer: The correct answer is a=\frac{v-u}{t}.

Explanation:

Retardation means negative acceleration. The acceleration is defined as the rate of change of  velocity. The example of applying: Brakes applied by moving car.

The expression for the acceleration is as follows;

a=\frac{v-u}{t}

Here, u is the initial velocity, v is the final velocity and t is the time.

If the initial velocity is greater than the final velocity then the above expression becomes the retardation.

Therefore, the expression for the retardation is a=\frac{v-u}{t}.
