Your nerf dart gun is able to shoot a suction cup dart at a speed of 5 m/s. your room is 3 meters across. you want to shoot your dart gun horizontally and hit the bulls-eye. how high above the bullseye would you need to aim for the dart to hit the spot you desire?

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.
