A racing car has a uniform acceleration of 4 m s-2. What distance will it cover in 10 s after start?

Answer :

Given,

Initial velocity, u = 0


Acceleration, a = 4 m/s2


And,


Time, t = 10 s


Distance covered, s =?


Now, s = ut + at2


= 0 × 10 +× 4 × (10)2


= 0 + 2 × 100


= 200 m


Therefore, in 10 seconds racing car will covered a distance of 200 m.
