Two forces act on an object with a mass of 5.0 kg horizontally. If one force of 60 N is applied to the right, and the object is accelerating at 3.0 m/s2 to the right, how much force should be applied to the left? 60 N
50 N
15 N
45 N

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.

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
