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".
