    K. E = 80 j

    Explanation:

    Given dа ta:

    Mass of box = 40 Kg

    Velocity = 2 m/s

    K. E = ?

    Solution:

    K. E = 1/2 m. v²

    K. E = 1/2 (40 Kg) (2 m/s) ²

    K. E = 1/2 (40 Kg) (4m²/s²}

    K. E = 1/2 (160 Kg. m²/s²)

    K. E = 80 Kg. m²/s²

    Kg. m²/s² = j

    K. E = 80 j
