My question is:

1)When an object falls to the ground, shouldn't the ground exert a force greater than the weight of the object to stop its motion altogether? Because if the forces experienced by the object the moment it strikes the ground are equal and opposite in direction, then that should only stop the object from accelerating further and it should continue moving with the velocity it had the instant before the forces cancelled. (I know it sounds silly for the ground because it's a solid, rigid body and can not allow the object to continue its motion through it. Maybe it'd be better if you replace the ground with a trampoline and explain it for that? )

Thank you for your time. :)
