There are 2 more parts to the question too : (b) Prove that the height from which the ball is dropped is 20m
(c) Prove that it would take 4.9s for a similar ball to drop 20m on the Moon. It is given that the gravitational field strength of the Earth’s gravitational field strength and that air resistance is negligible in both places.

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.
