Q. The volume of an ideal gas is increased from 0.7 m3 to 2.7 m3 while maintaining a constant pressure of 3000 Pa (1 Pa = 1 N/m2). If the initial temperature is 600K, what is the final temperature?

Q. A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6 m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2.
