Answer : The correct option is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Explanation :
Acceleration : It is defined as the change in velocity divided by the time.
The formula of Acceleration is,
So, we can calculate the acceleration only for 2nd option which is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
In this option, velocities and time are given.
In all the other options, the velocity and time are not given. So, we can not calculate the acceleration.
Hence, the correct option is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
