Chapter 287: A Bowl of Poisonous Chicken Soup

Let's be honest first, in fact, I think it's a very thing to explain fantasy things scientifically, for example, Xiahou summoned the Ming Gun, and said, this needs to be attractive enough, is Xiahou a big magnet? What else contains heaven and earth in the body, what Buddha light and divine brilliance, physics is nonsense.

But there are always some people who like to drill into the horns, especially the brainless black. I just saw someone chattering with an angle again, saying that Sang Sang didn't die after being shot by Xiahou, and he happened to be idle, so my brother will accompany you to analyze:

From a physical point of view, this is a typical process of a high-velocity object (Xia Hou's open gun) hitting a static object (the overall system of Sangsang and the big black umbrella).

The damage of the impact to Sangsang comes from the instantaneous impulse of the open gun caused by the change in initial velocity - stationary, which is a process quantity.

Since any object can be seen as an object with a certain elasticity, a faster impact has a certain amount of time, according to:

Impulse i=ft (impact force x time)

i=v1-v2 (change in momentum), the average force during the impact is f=(v1-v2)/t

That is to say, the impact force f ---- of the Sangsang human body at the time of impact is directly proportional to the change in momentum of the open gun, and inversely proportional to the time of impact.

The mass of the Ming gun is fixed, and the initial velocity v1 is also destined when Xiahou makes a move. So whether Sang Sang can withstand this move, the key is the speed of the open gun after the impact v2, and whether the impact time can be extended enough to withstand it.

From the original text:

The gun slammed into the big black umbrella, and the sharp tip of the spear pierced the grease and black mud of the years.

The place where the big black umbrella came into contact with the iron spear sank sharply, and the black cloth hissed, as if it had become a terrifying black hole, but at the bottom of the black hole, the tip of the spear was always ...... Didn't make it through the umbrella!

The handle of the big black umbrella was against the cliff stone, poof, like a knife cutting tofu, and then stabbed in, the stone and gravel flew around, closed his eyes, and the body of Sang Sang, who was hiding under the umbrella, shook heavily, and his face suddenly became extremely pale, and with a whoop, blood spurted out of his lips, staining the new clothes he had changed this morning. ”

Here we see three points:

1. From the "sharp sag through the umbrella surface", it can be seen that the impact time t has been greatly increased after the buffering of the umbrella surface. At the speed of the gun, if there is no black umbrella, the impact process is 01 seconds, and Sangsang is knocked away, and after the black umbrella, this collision process becomes 2 seconds, then it is equivalent to a 20-fold reduction in the impact force.

2. "Poof, like a knife cutting tofu, it will be stabbed in", it can be seen that after the impact, the whole system of the open gun-black umbrella-Sangsang has a certain speed, so it is not directly stationary after the impact (that is, the so-called "all are not connected"), that is to say, v2 is equal to 0, the impulse i=ft=v1-v2, if v2 increases, the momentum change will also decrease.

3. "The handle of the big black umbrella is against the cliff rock", that is to say, the main bearing point is not in the Sangsang human body, but the cliff behind.

Sang Sang is Wei Guangming's apprentice, the most talented divine art heir, with the above three points, and there is a cheating device like a black umbrella, Xiahou is seriously injured, what's so strange about not dying with one shot?
