Answer 2

Given :-

A body travelling with constant velocity of 200 m/s is brought to rest in 10 s

To Find :-

Retardation

Solution :-

We know that

a = v - u/t

a = 0 - 200/10

a = -200/10

a = -20 m/s²

Hence

Retardation is -20 m/s²

Other equation for motion

v = u + at

s = ut + 1/2 × at²

v² - u² = 2as
