Acar of mass m is going around a circular turn of radius r, which is banked at an angle β with respect to the ground. assume there is friction between the wheels and the road. let μs be the coefficient of static friction and g the magnitude of the gravitational acceleration. you may neglect kinetic friction (that is, the car’s tires do not slip). derive an expression for the range of possible speeds vmin ≤ v ≤ vmax necessary to keep the car moving in a circle without slipping up or down the embanked turn. express your answer in terms of some or all of the following: μs, β, m, r and g.

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.
