Solve each problem. See Examples 4 and 5If an object is projected upward from ground level withan initial velocity of 64 ft per sec, its height h in feett seconds later ish = -16t2 + 64t(a) After how many seconds is the height 48 ft?(b) The object reaches its maximum height 2 sec afterit is projected. What is this maximum height?(c) After how many seconds does the object hit the ground?(d) Find the number of seconds after which the height is 60 ft.(e) What is the physical interpretation of why part (d) has two answers?(f) The quadratic equation from part (c) has two solutions, yet only one of them isappropriate for answering the question. Why is this so?
