PROBLEM 11.141 Racecar A is traveling on a straight portion of the track while racecar B is traveling
on a circular portion of the track. At the instant shown, the speed of A is increasing at the rate of 10
m/s?, and the speed of B is decreasing at the rate of 6 m/s?. For the position shown, determine (a) the
velocity of B relative to A, (b) the acceleration of relative to A.
A=240km/h
B=200km/h with angle 50

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.
