A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function −16t2 + 45t + 3.5 , where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball’s descent, when was the football in the air at that height?
