    Answer:

    The displcament is 2.55m

    Explanation:

    step one:

    Given that the intial speed is

    u= 0.25 m/s

    and acceleration is

    a= 0.40 m/s^2

    and time t= 3seconds

    step two:

    Applying the formula

    s=ut+1/2at^2

    s= 0.25*3+ 1/2*0.4*3^3

    s= 0.75+3.6/2

    s= 0.75+1.8

    s=2.55 m

    The displacement is 2.55m
