If you have no way to avoid the punch, choice (1) is obviously better. But why? Let's look at the answer in terms of the impulse-momentum theorem, from the point of view of the hand. Q3: The change in momentum (mAv) of the hand is the same in (1) and (2) shown above. Carefully explain why. Now, since mAi for the hand is the same in both cases, and since mav = FAt, then FAt is the same in (1) and (2) for the hand. Thus, a small force acting over a large time period is equal to a large force acting over a small time period. This is shown in the previous picture with the size of %3D the letters
