Answer:

retardation = 3 m/sec²

Explanation:

speed of car, u = 108km/h

= 108*(5/18)m/sec

= 30m/sec

after car is stopped, v = 0 m/sec

distance covered by the car, s = 150m

using, v² = u²+2as

after putting values,

0 = 30²+2*(a)*150

300*a = -900

a = -3m/sec²

therefore retardation =3 m/sec²
