I'll presume that the Earth is a perfect spheroid (i.e., circle at the equator).

The rope will go around the equator for most of the way, and then will diverge at some point along the tangent of that circle, and then bend and do the reverse. Thus, the length of that tangent line is 1/2 meter longer than the circle arc that is subtended.

X = extra length up to bend

= 0.5 m

R = Earth's radius

= 6371000 m

θ = subtended angle (radians)

s = length of rope from leaving tangent to hitting the bend

h = height of rope at bend

s = R tan( θ ) = R θ + X

h = [ R / cos( θ ) ] - R = R ( 1 - [ 1 / cos( ( θ ) ]

tan( θ ) - θ = ( X / R ) ~= θ^3 / 3

θ = .0043

h = 58 m
