    Answer:

    Explanation:

                             GUN                                                                    BULLET

    mass, m  = 5 kg                                                    mass, m = 20 g = 0.02 kg

    initial velocity, u = 0                                              u = 0

    final velocity, v = ?                                                 v = 100 m/s

    v of the gun = m of the bullet × v of the bullet / m of the gun

    = 0.02 × 100 / 5

    = 2/5

    = 0.4 m/s

    Hope this helps

    plz mark as brainlliest!!!!!!!
