    Answer:

    The correct answer is “6.96 rad/s“.

    Explanation:

    The given values are:

    Length,

    L = 0.6 m

    Mass,

    m₁ = 0.5 kg

    m₂ = 0.2 kg

    Initial velocity,

    V = 8 m/s

    Now,

    The final angular velocity will be:

    ⇒ \omega =\frac{6m_1V}{(4m_1+3m_2)L}

    By substituting the values, we get

    ⇒     =\frac{6\times 0.2\times 8}{(4\times 0.2+3\times 0.5)0.6}

    ⇒     =\frac{9.6}{1.38}

    ⇒     =6.96 \ rad/s
