1. You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you
accelerate until you reach a comfortable velocity. Then you stop and switch places
with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable
velocity. Now, Tim may be bigger than you, but you have been working out and are
just as strong as Tim, so the force that Tim uses to pull the wagon is the same
force that you used. You both pull with the exact same amount of force. Who was
riding in the wagon when it had the greatest acceleration during start up? Why? Use
Newton's second law to explain.

2. Now Sara comes along, and she is the exact same size as you. However, she is even
stronger than you! When she pulls you in the wagon, she pulls with a greater force
than when you pull her. Now who is in the wagon when it has the greatest
acceleration? Explain, using Newton's second law.

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
