A student releases a marble at the top of a ramp and measures the distance the marble travels from
the end of the ramp. He conducts this experiment several times on different surfaces at the end of
the ramp, some rough and some smooth. He observes that the marble travels farther on the
smoother surfaces, but all of the marbles eventually stop.
How can this observation be explained by Newton's First Law of Motion?
The marble stops only when it is acted upon by an outside force.
The marble stops because its natural state is at rest.
The marble stops because of a normal force that is equal and opposite of gravity.
The marble stops only when gravity ceases to exert a force upon it.

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.
