    u1 = / frac{ (m1+m2) v}{m1}

    Explanation:

    In a perfectly elastic collision, the bodies move together with a common velocity after collison.

    let m1 represent the mass of body 1

    m2 for mass of body 2

    u1 is velocity of moving ball before collision

    u2 is velocity of stationary ball before collision

    v represents the common velocity of both bodies after collision.

    u2=0, (body 2 is stationary)

    we will substitute these variables into the formula

    m1u1 + m2u2 = (m1+m2) v

    m1u1 + m2 * 0 = (m1+m2) v

    m1u1 = (m1+m2) v

    u1 = / frac{ (m1+m2) v}{m1}
