A climber using bottled oxygen accidentally drops the oxygen bottle from an altitude of 4500 m. If the bottle fell straight down this entire distance, what is the velocity of the 3kg bottle just prior to impact at sea level? (Note: ignore air resistance) A. 300 m/s B. 150 m/s C. 30 m/s D. 3 m/s - As an object falls, the kinetic energy (KE) that it gains is equal to the potential energy (PE) that it loses. Thus, for this object, we can say that 1/2m(vfinal)2 = mgΔh, where g ~ 10 m/s2:...
