Since both vehicles are traveling at the same speed and have the same coefficient of static friction, they will both be able to stop in the same distance. The mass of the vehicles does not affect the stopping distance in this case, as both have the same braking force. The coefficient of kinetic friction is not relevant since the question only asks about stopping distance, not the motion of the vehicles after braking.
