Here we have, 

Acceleration, a = 4 m/s

Initial velocity, u = 0 m/s 

Time, t = 10 s 

Distance covered (s) =? 

We know that, s = ut + 1 /2 at2 

⇒ s = 0 × 10 + 1/ 2 × 4 × (10) 2

⇒ s = 2 × 100 m 

⇒ s = 200 m 

Thus, racing car will cover a distance of 200 m after start in 10 s with given acceleration.
