Approximately 0.1 % of the bacteria in an adult human's intestines are escherichia coli. these bacteria have been observed to move with speeds up to 15 μm/s and maximum accelerations of 166 μm/ s 2 . suppose an e. coli bacterium in your intestines starts at rest and accelerates at 157 μm/ s 2 . you may want to review (pages 40 - 43) . part a how much time is required for the bacterium to reach a speed of 12 μm/s ?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
