Both the cars would have same acceleration, then only car A is able to see zero acceleration of Car B. This is because, we know that car B is definitely accelerating as it is moving with speed [tex]v_B[/tex] in a circular path. Let the acceleration of Car B be [tex]\alpha_B=v_B/t[/tex], then [tex]\alpha_A=\alpha_B[/tex].
The two cars A and B would have same acceleration i.e. the rate of change their velocities would be equal.
