my original post had errors.
a train.
the begining of the track is 1000 feet straight up.
the track curves to a level section that is 10 miles long.
the train is 9 miles long.
each car is 100 ft long.
each car weighs 100,000 pounds.
at the 1000 ft tall section of track there
are (10) 100,000 pound cars that are pushing down
with a force of 1,000,000 pounds.
the remainder of the 9 mile long train is level to
the ground.
rolling friction steel against steel is .003
will the train move?
how much energy would it take to lift a 100,000 lb car to a height of 1000 ft?
if you lifted a car to this height each second and placed it on the track would the train reach a terminal velocity.
given that the train cars fall off at the end of the track.
after several hours of doing this would the total amount of kinetic energy of the moving train be more than the total energy required to lift the cars to the 1000 ft height?
now replace this with water and a pipe.
