    Kinetic energy of a moving object = (1/2 of the mass) x (speed²).

    Divide each side by (1/2 of the mass)

    and you get:

    Speed² = (KE) / (1/2 of the mass)

    Take the square root

    of each side: Speed = √ (2 · KE / mass).

    That's what you need, right there.

    If you know the kinetic energy, then ...

    - - double it,

    - - divide by the object's mass,

    - - take the square root.

    Now you have the object's speed.
