An astronaut of mass 150 kg is floating freely (at rest) in outer space. She is holding a 25 kg can (not part of her mass mentioned earlier). She throws the can forward with a velocity of 12 m/s. How fast will she move backwards after she throws the can?

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.

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?

The air that we breath is made mostly of which gaseous molecule
