Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second. The quarterback of a football team releases a pass at a height of 5 feet above the playing field, and the football is caught by a receiver 20 yards directly downfield at a height of 3 feet. The pass is released at an angle of 35° with the horizontal. (a) Find the speed of the football when it is released. (Round your answer to three decimal places.) ft/sec (b) Find the maximum height of the football. (Round your answer to one decimal place.) ft (c) Find the time the receiver has to reach the proper position after the quarterback releases the football. (Round your answer to one decimal place.) sec

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.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
