Suppose that a sled is accelerating at a rate of 2 m/s^2. if the net force is tripled and the mass is doubled, then what is the the new acceleration of the sled?

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.
