Problems for discussion and to solve algebraically: Given s(t) = -16 t + 32 t + 48, where t=0 represents the time that object is released (thrown upward). 1.1 What is s(0) and what does it represent? 1.2 What is the value of s when the object hits the ground? How many seconds (from time of release) will it take for the object to hit the ground? 1.3 What is the relevant domain for the model? (what values for t make sense?) 1.4 What does a sketch of y = s(t) look like? 1.5 At what time does the object attain a maximum height? What is the maximum height
