3) The graph of the velocity , in ft/sec, of a car travelingon a straight road, for is shown in the figure.
a) Find the average acceleration of the car, over the interval
b) Find an approximation for the acceleration of the car at t = 20.
c) Approximate with a Riemann sum, using the midpoints of three subintervals of equal length. Explain the meaning of this integral.
4) (modification of 2006 BC 4)Rocket A has positive velocity v(t) after being launched upward from an initial height of 0 feet at time t = 0 seconds. The velocity of the rocket is recorded for selected values of t over the interval seconds as shown in the table below
t (seconds) 0 10 20 30 40 50 60 70 80

4) (modification of 2006 BC)b) Rocket B is launched upward with an acceleration
of
feet per second per second. At time t=0 seconds, the initial height of the rocket is 0 feet, and the initial velocity is 2 feet per second. Which of the two rockets is traveling faster at t = 80 seconds?
