Chapter 7, Problem 219

(choose chapter or problem)

Calculating average and instantaneous velocities Suppose the heights of an object (in m) above the ground after t seconds is approximated by the function \(s=f(t)=-4.9 t^{2}+25 t+1\).

a. Make a table showing the average velocities of the object from time t = 1 to t = 1 + h for h = 0.01, 0.001, 0.0001, and 0.00001.

b. Use the table in part (a) to estimate the instantaneous velocity of the object at t = 1 s.

c. Use limits to verify your estimate in part (b).
