- 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 6,267 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?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
