Question

Two globs of molten rock are in outer space. One glob has a mass of 2,400 kilograms and is moving at a velocity of 680 meters per second directly toward the second glob. The second glob is at rest. The two globs collide in a perfectly inelastic collision—sticking together. If the velocity of the new mega-glob is 90 m/s, what was the original mass of the second glob? A. 318 kg B. 213,600 kg C. 15,733 kg D. 15,708 kg

    Answer:

    C. 15,733 kg

    Explanation:

    Conservation of momentum

    2400(680) + m(0) = 2400(90) + 90m

    2400(680 – 90) = 90m

    m = 15,733.3333333…
