Abaseball pitcher throws a ball at 97.0 mi/h in the horizontal direction. how far does the ball fall vertically by the time it reaches home plate, which is a horizontal distance of 60.5 ft away? (express your answer in units of feet. neglect air resistance.)

What are chlorofluorocarbons and what impact do they have on the atmosphere?

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

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.
