An object is thrown upward from a height of 6 feet at a velocity of 60 feet per second. t1 = 0, t2 = 3 (A) Use the position equation s = 16t^2 + v0t + s0 to write a function that represents the situation. (B) graphing utility to graph the function. (C)Find the average rate of change of the function from t1 to t2. (D) Find the equation of the secant line through t1 and t2. (E) Graph the secant line in the same viewing window as your position function
