The compression ratio of an Otto cycle as shown in the figure below is VA/VB = 6.00. At the beginning A of the compression process, 525 cm3 of gas is at 110 kPa and 20.0°C. At the beginning of the adiabatic expansion, the temperature is TC = 730°C. Model the working fluid as an ideal gas with γ = 1.40.

Arescue plane flying horizontally at spots a survivor in the ocean directly below and releases an emergency kit with a parachute. because of the shape of the parachute, it experiences insignificant horizontal air resistance. if the kit descends with a constant vertical acceleration of, how far away from the survivor will it hit the waves?
