Question

Multiple-Concept Example 17 reviews the basic concepts involved in this problem. Air rushing over the wings of high-performance race cars generates unwanted horizontal air resistance but also causes a vertical downforce, which helps cars hug the track more securely. The coefficient of static friction between the track and the tires of a 719-kg car is 0.860. What is the magnitude of the maximum acceleration at which the car can speed up without its tires slipping when a 3530-N downforce and an 1350-N horizontal air resistance force act on it?

Explanation / Answer

F = ma = f=N

a = N/m = 0.907 * (1320+4820)/683 = 8.154 m/s2
