The peak of the extinct volcano Volcán Chimborazo in Ecuador is the farthest point on Earth from Earth's center. This is because Earth bulges outward due
to its rotation, and this bulge is greatest at the Equator, which is only about
100 km north of Chimborazo. Volcán Chimborazo's summit is 6267 m above
sea level. If a mountain climber with a mass of 85 kg (climbing equipment
included) reaches the mountain's peak, what is the gravitational potential
energy associated with the climber with respect to sea level?
