The "cornering performance" of an automobile is evaluated?

Question

The "cornering performance" of an automobile is evaluated on a skid pad, where the maximum speed that a car can maintain around a circular path on a dry, flat surface is measured. Then the centripetal acceleration, also called the lateral acceleration, is calculated as a multiple of the free-fall acceleration g. The main factors affecting the performance of the car are its tire characteristics and the suspension system. A certain car can negotiate a skidpad of radius 62.2 m at 80.5 km/h. Calculate its maximum lateral acceleration.

Answer 1

The centripetal force (toward the center) required to make the car follow the circular path is given by
Fc = m*v^2/r

Convert your speed data into m/s and plug in your data. Leave the m, mass, in the expression as just m. From the familiar equation
F = m*a,
you can see that if you drop the m from your result to the equation
Fc = m*v^2/r
you are left with acceleration. If that acceleration is 2X g (9.8 m/s^2) then it was 2g.
