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?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
