Physics question a spacecraft descends vertically near the surface of planet x. an upward thrust of 25.0kn from its engines slows it down at a rate of 1.20 m/s^2, but if an upward thrust of only 10.0 kn is applied, it speeds up at rate of .80m/s^2.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
