A hockey puck with a mass of 0.17 kg is traveling to the right along the ice at 15 m/s. It strikes a second hockey
puck with a mass 0.11 kg. The first hockey puck comes to rest after the collision. What is the initial
momentum of the system? (Round your answer to the nearest tenth.)

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.
