the formul for retardation is same as the formula for accelaration which is v-u/t...

but when we say retardation it means we are moving in the opposite direction of motion so in that case the anwser which we will get will be negative.

for example if the acceleration is 2m/s2 then the retardation is -2m/s2

A body is moving in a straight line and its displacement at various instants of time is given in the following:
Time(s): 0 , 1,2,3,4,5,6,7
Displacement(m): 2,6,12,12,18,22,24
Plot displacement time graph and calculate:
(i) total distance travel in interval 1s
to 5s.
(ii) average velocity in time interval 1s to 5 s.

If you are questioned to calculate the retardation then you can simply calculate the acceleration and put a -ve sign on the answer or you can use the formula u-v/t. This formula is also derived from v-u/t but as we know retardation is negative acceleration so you can use the formula. v-u/t
