Comic Book Physics 101.
Ok so we've all seen some things go down in comics that seem to fly in the face of real world physics, so this is the place to ask questions and get details on some of the specifics involving them from some of the more academically inclined KMC members. Things like...
1. How hard would Captain America have had to throw his shield to hit that missile?
2. How much force does it really take to push a planet?
And consider theoretical questions fair game also. For instance...
Suppose some hero(who has superspeed) is capable of throwing a punch at 10 times the speed of sound. Now I know that a sonic boom is created by an object surpassing the sound of it's own movement(or at least something to that effect) so my question is what happens when the hero throws 3 punches at 10 times the speed of sound and they all land before the sound waves of the initial punch reach the target? Think about it, it seems like there should be one sonic boom for the initial punch, another when the heroes hand reverses it's direction and breaks the sound barrier again, and then TWO more as the second punch passes it's own sound waves and the sound waves of the first punch, one more for the reverse in direction again, and then THREE more as the third punch passes all three sets of sound waves. So there should be 8 sonic booms going off at pretty much the same instant as a result of the three punches. Now am I right, or is my line of thinking off?
