Adock worker loading crates on a ship finds that a 24 kg crate, initially at rest on a horizontal surface, requires a 65 n horizontal force to set it in motion. however, after the crate is in motion, a horizontal force of 50 n is required to keep it moving with a constant speed. the acceleration of gravity is 9.8 m/s 2 . find the coefficient of static friction between crate and floor.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
