Awhite car is traveling at the legal speed limit v0 along an interstate highway. a blue car traveling in the same direction at twice the legal limit draws alongside the white car and (mistakenly) thinks it is a police car. the blue car slows down with constant acceleration a = −ab and the white car continues at its previous constant speed. how far apart are the cars when the blue car’s speed is the legal speed limit?

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.
