An airplane with mass 200,000 kg is traveling with a speed of
268 m/s the kinetic energy of the plane speed is 7.18 x 10'J.
A wind picks up, which causes the plane to lose 1.20 x 10 J per
second. How fast is the plane going after 25.0 seconds?
a
250.207 m/s
b 204.509 m/s
c
190.423 m/s
d
144.527 m/s

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
