If 270 kg tiger running at 13 m/s tackles a 130 kg terrified physics teacher run/jogging as best as he can at 8.5 m/s away from the tiger. What is the velocity of the combined mass once the tigers ferocious maw locks on to his shoulder?

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.
