Answer:
object b has more inertia as inertia is mass dependent ; object a and b both possess same momentum as product of mass and velocity is same in both cases ; force required to stop the bodies in the same time is also the same for both bodies as force is rate of change of momentum using newtons 2 nd law of motion
