Ineed understanding this physics question on my homework. could someone ? romeo is throwing pebbles gently up to juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. he is standing at the edge of a rose garden h = 9.8 m below her window and l = 9.7 m from the base of the wall. how fast are the pebbles going when they hit her window? express your answer to two significant figures and include the appropriate units.

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.
