In outer space, a constant force is applied to a 34.0 kg probe initially at rest. The probe moves a distance of 105 m in 14 s.

Part A
What acceleration does this force produce?
Express your answer in meters per second squared.

Part B
What is the magnitude of the force?
Express your answer in newtons.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
