Railways

Railways climb 2.8 ‰.

Calculate the height difference between two points on the railway distant 5997 meters.

Final Answer:

y =  16.79 m

Step-by-step explanation:

r=2.8‰=10002.8​=0.0028 s=5997 m  s2 = x2+y2 y:x = r  s2 = (y/r)2+y2 s2 = y2/r2+y2 s2 = y2(1+1/r2) s = y⋅ 1+1/r2​  y=1+(1/r)2​s​=1+(1/0.0028)2​5997​=16.79 m
