Determine (a) the speed with which the train needs to travel on a curved section of the track if the magnitude of the side force to be felt by a passenger of weight � in a standard car with no tilt is 0.20�, (b) the required angle of tilt � if the passenger is to feel no side force when the train is traveling at 180 km/h. Notice that a side force is defined here as a force that is parallel to the floor of the car; and the rated speed of a curved section of track is defined as the speed at which a train should travel if no lateral friction force is to be exerted on its wheels.

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.
