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