5. At last, it's time to go diving! You are going to dive offshore, but you'll need to drive to the site. You load your gear into the trunk of the car and take off. (10 points)

a. What type of device does the car use to move? Describe in terms of the second law of thermodynamics, and draw a diagram of how this device operates. (6 points)

An air-standard Stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. The maximum volume of the air is 10 times the minimum volume. The temperature during the heat rejection process is 100°F. Calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. Use constant specific heats at room temperature.

Was your prediction about Marial’s fate correct? If not, what clues in the text foreshadowed this?

If at point two, the 75 kg coaster is traveling 17 m/s, what is the kinetic energy? If the total mechanical energy is 15,000 J, what is the potential energy?

A large fish with a mass of 3.5 kg is swimming due east with a velocity of 4.7 m/s it swallows a much smaller fish with a mass of 0.4 kg that is initially at rest afterwards the two fish move together with the same velocity what is the magnitude and direction of their final velocity round to the nearest 10
