    Answer:

    1.1 m/s

    Explanation:

    Applying,

    v = u+at………….. Equation 1

    Where v = final velocity, u = initial velocity, a = acceleration, t = time.

    From the question,

    Given: u = 0.3 ms, a = 0.4 m/s², t = 2 seconds

    Substitute these values into equation 1

    v = 0.3+0.4(2)

    v = 0.3+0.8

    v = 1.1 m/s

    Hence the velocity at the end of 2 seconds is 1.1 m/s
