Julio decides to break the Guinness Book of World Records for bungee jumping. He goes to the Macau Tower in China where the current record is held. After several heart-pounding
seconds, he leaps from a height of 233 meters. If his weight is 86 kilograms, what would his
potential energy be just prior to jumping? If when he jumped he reached a speed of 15 m/s, what
is his kinetic energy? Explain your answer

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
