• B. Hitting a piece of sponge will hurt more
• C. Both will hurt equally
• D. No comparison between two

Answer 1

The correct option is A Hitting a wall will hurt more

Hitting a wall will hurt more than hitting a piece of sponge. This can be explained as follows-Wall is hard, When you hit a wall, an equal reaction force acts on the hand and hurts it.

When you hit a piece of sponge, a part of the momentum of hand is transferred to the sponge. As a result, it gets deformed and the reaction is much less than the action.
