A jet aircraft with a mass of 4,325 kg has an engine that exerts a force (thrust) equal to 60,500 N while experiencing a resistive force of 1,820 N during take off (a).         What is the jet’s acceleration in m/s2 and in g’s when it takes off?                                                  (3.5 points)   (b).         What is the jet’s speed after it accelerates for 5.0 s? (Assume it starts from rest.)                           (1.5 points) (c).         How far does the jet travel during the 6.5 s?                                                                                      (1.5 points)

 Which of the following methods of heat transfer generally involves mass movement?  

(a).      A quantity of gas in a piston cylinder has a volume of 0.392 m3 and a pressure of 200 Pa. The piston compresses the gas to 0.250 m3 in an isothermal (constant-           temperature) process. What is the final pressure of the gas?                                                                                                                                         (1.5 points)   b).          A closed rigid container holds a particular amount of hydrogen gas.
