A man standing at the top of a building kicks a small rock of massm. The height of the building ishand initialvelocity of the rock after the kick is~v =< v,0,0>. Assume no air resistance and let g be the magnitude of the acceleration due to gravity. a. Find the time taken by the rock to hit the ground.
b. How far away from the building did the rock travel before hitting the ground?
c. Determine the magnitude of velocity of the rock before hitting the ground.

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.
