Answer:
Yes,the acceleration is uniform
Explanation:
Acceleration = Change in velocity/time taken
In the first two seconds,
Acceleration = [(33.6 - 30)/2] km/h2
= 1.8 km/h2
= 0.5 m/s2 …(i)
In the next two seconds,
Acceleration = [(37.2 - 33.6)/2] km/h2
= 1.8 km/h2
= 0.5 m/s2…(ii)
From (i) and (ii), we can say that the acceleration is uniform.
