A racing car has a uniform acceleration of 4 m s-2. What distance will it cover in 10 s after start?
ScienceClass 9CBSEAnswered 27 Mar 2026
Answer
Solution
Given, the car is initially at rest; initial velocity (u) = 0 ms-1
Acceleration (a) = 4 ms-2
Time period (t) = 10 s
As per the second motion equation, s = ut+1/2 at2
Therefore, the total distance covered by the car (s) = 0 * 10m + 1/2 (4ms-2)(10s)2
= 200 meters
Therefore, the car will cover a distance of 200 meters after 10 seconds.
