Question

A racing car has a uniform acceleration of 4 m/s² . What distance will it cover in 10 s after start?

Answer 1

Here we have, 

Acceleration, a = 4 m/s² 

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 m 

⇒ 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.
