Ajet aircraft is traveling at 262 m/s in hor-
izontal flight. the engine takes in air at a
rate of 85.9 kg/s and burns fuel at a rate of
3.92 kg/s. the exhaust gases are ejected at
921 m/s relative to the aircraft.
find the thrust of the jet engine.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

radiation warms things up temp rises convection currents air circ windy weather
