Ball a is thrown vertically upwards with a velocity of v0 . ball b is thrown upwards from the same point with the same velocity t seconds later.
part a
determine the elapsed time t< 2v0/g from the instant ball a is thrown to when the balls pass each other .
express your answer in terms of some or all of the variables v0, t, and the acceleration due to gravity g .

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.
