    Answer:

    V_{f} = 6 cm/s

    Explanation:

    Given:

    Acceleration = a = 2 cm/s²

    Time = t = 3s

    Initial Velocity = V_{i} = 0 cm/s

    Required:

    Velocity = V_{f} = ?

    Formula:

    a = \frac{V_{f}-V_{i}}{t}

    Solution:

    2 = \frac{V_{f}-0}{3}

    => V_{f} = 2*3

    => V_{f} = 6 cm/s
