Three stock car drivers are racing around a circular bend. They are each circling the bend at different radii: r(1)=249 m , r(2)=255 m , and r(3)=261 m . At a given instant, all three are traveling at the same transverse rate of rotation, .259 rad/s .The cars are also increasing their transverse rate of rotation by the same rate, 2.59x10^-2 rad.s^2. Determine the magnitudes of the velocity and acceleration of the first two drivers?
