Aball is thrown straight up from the top of a tower that is 280 ft high with an initial velocity of 48 ft/s. the height of the object can be modeled by the equation s ( t ) = -16 t2 + 48 t + 280.
determine the time(s) the ball is lower than the building. express your answer in interval notation. in two or more sentences, describe your solution method.
