A 15,000 kg rocket traveling at +230 m/s turns on its engines. Over a 6.0 s period it
burns 1,000 kg of fuel. An observer on the ground measures the velocity of the expelled
gases to be -1,200 m/s.
c. What impulse is applied to the rocket? Your answer will be in kg*m/s with no scientific
notation
Please help ASAP :)

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.
