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?

Question

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.

Answer 1

Object B since lighter objects have less inertia and therefore require less force to stop.

Answer 2

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 B since lighter objects have less inertia and therefore require less force to stop.

Object A since heavier objects tend to have more momentum and therefore require more force to stop.
