    Answer:

    Tt will take 4.04 seconds

    Explanation:

    In this problem/exercise, we are going to apply the newtons first equation of motion to solve for the time taken

    Given that

    final velocity= 3.4m/s

    initia velocity u= 0m/s

    deceleration= 0.84 m/s^2

    time t= ?

    applying

    v=u+at

    Substituting our given data into the expression above we have

    3.4=0+0.84t

    3.4=0.84t

    divide both sides by 0.84 we have

    3.4/0.84= t

    t= 4.04 seconds
