The table* gives automobile performance data for a few types of cars:

(a) During an acceleration of 0 to 60 mph, which car has the largest average net force acting on it? The smallest?

(b) During this acceleration, for which car would the average net force on a 72.0 kg passenger be the largest? The smallest?

(c) When the Ferrari F430 accelerates from 0 to 100 mph in 8.6 s, what is the average net force acting on it? How does this net force compare with the average net force during the acceleration from 0 to 60 mph? Explain why these average net forces might differ.
(d) Discuss why a car has a top speed. What is the net force on the Ferrari F430 when it is traveling at its top speed, 196 mph?
