    Answer:

    125000 m/s.

    Explanation:

    The superman is pushing the spaceship in universe and we know there is absence of air or other interfering forces so in this case the total momentum will be conserved.

    So, we can write

    m_1v_1=m_2v_2

    Where,

    m_1 = mass of spaceship

    v_1 = speed of spaceship

    m_2 = mass of superman

    v_2 = speed of superman

    Now, putting the values given in the question in the above equation,

    150 × 125000 = 150 × v_2

    Solving for v_2 we get,

    v_2 = 125000 m/s

    Thus the speed of superman after pushing the spaceship will be 125000 m/s.
