Velocity of a car suppose the distance s in feet covered by


Qusetion: VELOCITY OF A CAR Suppose the distance s (in feet) covered by a car moving along a straight road after t sec is given by the function a = f(t) = 2t2 + 48t.

a. Calculate the average velocity of the car over the time intervals [20, 21], [20, 20.1], and [20, 20.01].

b. Calculate the (instantaneous) velocity of the car when t = 20.

c. Compare the results of part (a) with that of part (b).
