In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question.
Initial velocity = 25 m/s
Final velocity = 0 m/s
Initial time = 0 second
Final time = 5 second
Now we can write an equation to determine the acceleration.
Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time)
= (0 - 25)/ (5 - 0)
= - 25/5
= -5 m/s^2
So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".
