A car is moving on a straight road with a speed of `20 m//s`. The drive of the car put the breaks at some instant which retards the car uniformly at a rate of `2 m//s^(2)`, until the car stops completely then find the time `(t_(0))` taken by the car and distance `(d)` travelled by car, from the instant the drive put the breaks till it stops:
