A rabbit hops at 2.50 m/s east for 2.00 minutes, and then stops for 30.0 seconds. The rabbit then hops at 3.00 m/s east for 60.0 seconds.
a) Find the rabbit's displacement from its starting point.
b)Find the rabbit's average speed for its full journey (including the stop).

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.
