Ablock of mass 4 kg sliding on a horizontal plain is released with a velocity of 2.9 m/s the block slides and stops at a distance of 2 m beyond the point where it was released. how far would the block have slid if it’s initial velocity were increased by a factor of 2.1?

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.
