The correct answer is: Object B since lighter objects have less momentum.
When objects have the same speed, the momentum of an object is directly proportional to its mass. Therefore, if Object A is relatively heavier than Object B, it will have more momentum. To stop an object, a force needs to be applied in the opposite direction of its motion, and this force is directly related to the object's momentum.
Since Object A has more momentum, it will require more effort to stop compared to Object B. Object B, being lighter, will have less momentum and therefore require less effort to stop.
Two objects with the same speed need to stop. Object A is relatively heavier than Object B. Considering that both objects are in the same environment, which will require less effort to stop?
Object A since heavier objects tend to slow down on their own.
Object B since lighter objects has less momentum.
Object A due to its larger kinetic energy that can easily be translated to potential energy.
Object B since friction has greater effect on light objects.
Object A and B will stop at the same time since mass does not affect motion.
