Unformatted text preview: since the bottom-most point of the car tire is instantaneously at rest with respect to the race track, just as static friction applies to the contact surface between cat and platform. Using Eq. 6-23 with Eq. 4-35, we find s = (2 R/T ) 2 / gR = 4 2 R/gT 2 . With T = 6.0 s and R = 5.4 m, we obtain s = 0.60....
