In Example 2.1.2, we show how slope and a rate of change can be computed analytically using a limit. FIGURE 2.2 Inflation as a function of unemployment. If air resistance is neglected, an object dropped from a great height will fall s(t) 16t 2 feet in t seconds. A. What is the object”s velocity after t 2 seconds? B. How is the velocity found in part (a) related to the graph of s(t)?
