Question 1185028: Suppose a railroad rail is 2 kilometers and it expands on a hot day by 12centimeters in length. Approximately how many meters would the center of the rail rise above the ground? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Suppose a railroad rail is 2 kilometers and it expands on a hot day by 12centimeters in length.
Approximately how many meters would the center of the rail rise above the ground?
:
Change 2 km to 2000 meters and 12 cm to .12 meters
This forms a triangle with two equal sides of 1000.06 meters and the base of 2000 meters.
The height of the triangle divides it into two right triangles which we can solve. a^2 + b^2 = c^2, where
a = 1000 m, b = the height and c = 1000.06 m
1000^2 + b^2 = 1000.06^2
b =
using the calc
b = 10.9546 meters which seems not possible, but there it is
