    Correct answer: Ek = I² / 2 · m

    Explanation:

    The formula by which kinetic energy is calculated is:

    Ek = m V² / 2

    The formula by which momentum i prefer the name impulse is calculated is:

    I = m V

    We will transform the formula for kinetic energy on the next way:

    Ek = m V² / 2 we will multiply numerator and denominator with m and get:

    Ek = m² V² / 2 m = (m v) ² / 2 m = I² / 2 m

    Ek = I² / 2 m

    God is with you!
