No the answer is 200 as the car is having a uniform acceleration of 1m/s².So, according to the formula s=ut 1/2at², the distance covered (s) = 0 1/2at²=1/2x1x400=200m.

No the answer is 200 as the car is having a uniform acceleration of 1m/s^2.So, according to the formula s=ut 1/2at^2, the distance covered (s) = 0 1/2at^2=1/2x1x400=200m.
