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 651-kg car is 0.760. What is the magnitude of the maximum acceleration at which the car can speed up without its tires slipping when a 4550-N downforce and an 1130-N horizontal air resistance force act on it?
-
(651 x 9.8) + 4550 = total downforce of 10,929.8N.
Friction force acting at max. downforce = (10,929.8 x .760), = 8,306.648N.
(8,306.648 - 1130) = net accelerating force of 7,176.648N.
Max. acceleration = (F/M), = 7,176.648/651, = 11.024m/sec^2.
