This is conceptual. Its requiring an explanation no calculation. The topic is impulse, momentum and energy. It says there are two answers as to what happens if you switch the hammer to rubber. 1. is its less effective as the time of contact increases. 2. is its more effective as the change in...

How does that affect it if we're considering a closed system.

The time of impact will increase for the rubber hammer, so for the same change in momentum the force decreases. So if the force needed to change the hammers momentum is less, +considering Newtons 3rd law, therefore, the force on the nail is less. But if the change in momentum remains the same...

@haruspex, your first post What would be the difference? I assume your applying the force as your wielding the hammer and the nail is providing the change in momentum as its stopping the hammer.

This is what evie and irene Curie must of felt like

My intuition went to bed at 11.

Rubber

The rubber hammer is more elastic so the time of contact will increase. Ft=m(v-u) Does this mean it is more effective as less force is needed for the same change in momentum of the hammer (and the nail) so it requires less force from you? Or does it mean it is less effective as it imparts less...
