Question

formulla of retardation​

Answer 1

Explanation:

As there is no actual formula. Retardation or deceleration is negative change in velocity per unit time. So, Here, retardation=change in velocity/time(seconds).

Answer 2

Answer:

Retardation= u-v/t

Explanation:

Retardation- The change in velocity in unit time is called retardation but is a special case of acceleration, and is obtained only if final velocity is smaller than initial velocity, or say when the body is coming to rest.

Well, the formulae of acceleration of is v-u/t so, as we know retardation is opposite of acceleration, the formulae becomes u-v/t.
