A spacecraft carries a small amount of matter–antimatter fuel. During an emergency all of the fuel, having a total mass of 2.0g, is completely converted into useful energy.
(i) Calculate the total energy that becomes available. Express your answer in joule.
(ii) If the entire energy obtained in part (i) is used to lift a 1.0×103kg rescue capsule vertically near Earth’s surface, ignoring air resistance and assuming g=9.8ms−2, find the maximum height that the capsule can reach.
