A 3.0 kg solid cylinder (radius = 0.15 m , length = 0.65 m ) is released from rest at the top of a ramp and allowed to roll without
slipping. The ramp is 0.90 m high and 5.0 m long.
A) When the cylinder reaches the bottom of the ramp, what is its total kinetic energy?
Express your answer using two significant figures.
B) When the cylinder reaches the bottom of the ramp, what is its rotational kinetic energy?
Express your answer using two significant figures.
C) When the cylinder reaches the bottom of the ramp, what is its translational kinetic energy?

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.
