    125000 m/s

    Explanation:

    From the law of conservation of linear momentum, the sum of initial and final momentum are zero. Momentum is given as p=mv where p represent momentum, m is mass of an object and v is the velocity. In this case, the initial momentum is zero since both are stationery. The final momentum sums should also be zero.

    Final momentum

    Mass of superman*speed + Mass of spaceship*speed of spaceship=0

    150v + (125000*150) = 0

    150v = (12500*-150)

    v=-12500 m/s

    Therefore, the superman will have a speed of 12500 m/s in opposite direction of the spaceship
