    Answer:16624.2m/s

    Explanation:

    mass (m) = 0.55g=0.55/1000=0.00055kg

    Kinetic energy (ke) = 7.6 x 10^4 j

    Velocity=√ ((2xke) ➗ m)

    Velocity=√ ((2x7.6x10^4) ➗ 0.00055)

    Velocity=√ (152000 ➗ 0.00055)

    Velocity=√ (276363636.4)

    Velocity=16624.2

    Velocity=16624.2m/s
