Chapter 211 Written Test
"Sakura..." Ino glanced cautiously at Satsuki not far away and asked in a low voice, "Satsuki... didn't do anything to you, did she? Are you getting along... well with your teammates?"
Having once unexpectedly witnessed the arrogant Uchiha's second daughter preparing such an ambiguous gift for someone else, Ino was warned and left with an indelible psychological shadow. At this moment, her tone still carried a trace of lingering fear.
Sakura was a little puzzled as to why her usually cheerful and confident friend seemed so timid. Was she too nervous about the Chunin Exams? But she still answered earnestly.
"Yeah! Naruto and Satsuki have been really kind to me, and I'm so grateful to them. I feel so lucky to be in the same group as Satsuki! We're friends now."
"Ino, you know what? Don't let Satsuki's seemingly cold demeanor fool you; she's actually very gentle and considerate."
Sakura excitedly shared her joy with Ino, her cheeks flushing slightly with excitement.
Ino was completely dumbfounded after hearing this. Gentle? Considerate? How exactly could these two words be combined to describe that Uchiha?
Could it be... that Sakura is subjected to some strange genjutsu before each mission? No, a Jonin instructor wouldn't allow that to happen...
"That's rare, everyone's here! Naruto! How have you been lately?"
On the other side, Kiba, Hinata, and Shino also found their former classmate. Kiba, with a cheerful smile, warmly put his arm around Naruto's shoulder, looking like the two buddies.
Kiba and Naruto have a very good relationship now.
"Woof!"
Akamaru, perched atop his head, barked excitedly and nuzzled affectionately against Naruto's hair. This little ninja dog had always been fond of the boy who often gently stroked it and fed it delicious food.
"Kiba, it's been a long time." Naruto responded to the enthusiasm with a smile.
However, the next second, Satsuki intervened between the two with a blank expression, pulling Kiba away from Naruto.
"Don't put your arms around each other like that," Satsuki said calmly. "Naruto will find it bothersome."
Zuo Yue felt utterly exasperated by this clueless guy. It seemed he hadn't understood a thing of the subtle warnings she'd given him earlier.
"Ah, here we go again," Kiba said, scratching his head. "You're still the same as always, Satsuki."
Naruto looked around at his classmates, who were chatting enthusiastically. The familiar scene filled him with emotion. Just like in the original work, the new generation of elites of Konoha—his classmates from the "Nine Konoha ...
Unlike the original timeline, since Satsuki is a woman, Sakura and Ino are currently holding hands intimately, looking like best friends.
But... Naruto was puzzled as to why Ino still looked so timid and hesitant. Even now, Naruto still didn't understand why Ino would become inexplicably nervous whenever she was near him.
By the way, according to the original storyline, shouldn't Lee have blocked the way and challenged Sasuke before entering the classroom? Why didn't he make a move this time?
At the same time, Naruto's gaze locked onto a seemingly gentle but actually dangerous figure in the crowd—silver-gray hair, round-framed glasses, and a harmless smile on his face. This was none other than Orochimaru's right-hand man, Kabuto Yakushi.
But Naruto felt sorry for this guy... It seems Orochimaru is indeed preparing to take action.
"Quiet down, all of you! You bunch of useless trash!"
A furious shout suddenly erupted from the direction of the podium, instantly silencing the noise in the room. Everyone's eyes turned to the source of the sound. Accompanied by smoke, Morino Ibiki, dressed in a black trench coat with a cold expression, led a group of examiners, including Kamizuki Izumo and Kotetsu, making a majestic entrance with an aura of menacing men.
"I'm sorry to have kept you waiting." Ibiki's cold gaze swept across the entire room. "I am Morino Ibiki, the examiner for the first session of the Chunin Selection Exams."
"The first session of the Chunin Selection Exams will begin immediately. After submitting your applications, please collect your number tags and take your seats in the designated areas. Next, the written exam papers will be distributed."
------
"Everyone's been separated..."
After finding his seat according to his number, Naruto discovered that Satsuki and Sakura had been assigned to seats further away. Looking at Hinata sitting next to him, shyly smiling and nodding at him, Naruto returned a gentle smile. At the same time, he felt the exam was rather boring.
After all the candidates were seated, Ibihi tapped the blackboard heavily with chalk and began to read out the exam rules.
"There are several crucial rules in the first round of selection. I will not accept any questions, so listen carefully."
"First, each candidate starts with 10 points. The written test consists of 10 questions, each worth 1 point. This exam uses a penalty system—one point is deducted for each incorrect answer."
"Secondly, exam results will be judged based on the total score of the three members in each group."
"Most importantly, if you are found to have cheated during the exam, or are suspected of cheating—you will be deducted 2 points on the spot for each instance!"
"If you want to become a Chunin, you should act like an excellent ninja."
"Furthermore, if any one of the three scores zero, the entire team will be immediately disqualified. Finally—the tenth question will be announced 45 minutes after the start of the exam."
"The exam will last one hour. Now—begin!"
At Ibiki's command, the examinees opened their exam papers. Naruto looked down at the question and saw a typical ninja theory question that combined parabolic trajectory and practical analysis.
Parabola B in the diagram represents the maximum trajectory of a shuriken thrown by an enemy ninja A standing on a seven-meter-high tree. Please describe the characteristics of enemy ninjas that may appear within this throwing range, the maximum range in a two-dimensional battle, and the basis for your calculations.
Naruto decided to think it over before cheating.
Ok……
Naruto first focused his attention on the characteristics of the enemy ninja within the range of the parabolic trajectory.
When enemy ninja A throws a shuriken from a seven-meter-high tree at maximum range, the trajectory of the parabola B determines the characteristics of the target that can be hit.
At the end of its range, the shuriken's height approaches zero, almost touching the ground. This means that for an enemy to be hit at this position, their vital parts—such as the head or chest—must be within the effective killing range of their parabolic trajectory.
Naruto lightly traced the parabola diagram on the test paper with his fingertip, quickly constructing a three-dimensional spatial model in his mind.
More precisely, the y-coordinate defines the shuriken's flight height over the entire horizontal distance covered by its parabolic trajectory. An enemy who can be hit must have their vital organs within the "danger zone" defined by this constantly changing y-value.
This means that the target's height cannot deviate too much from a certain range—it cannot be too tall so that the vitals exceed the highest point of the trajectory, nor too short so that the vitals are always below the minimum effective hit height of the trajectory.
After a brief mental calculation and spatial imagination, he arrived at his first conclusion.
Therefore, the most reasonable answer should be "an enemy with a height of about 1.7 meters". Because for a ninja of this height, there is a high probability that their chest or head, when standing, would be within the range of the vertical coordinates of various points on the effective range of the parabola B.
Next is the second part – maximum range in planar combat.
When both sides are on a flat surface and the height advantage is lost, the maximum range needs to be recalculated. According to the laws of projectile motion, with a constant initial velocity, the range is greatest when the launch angle is 45 degrees.
Given a height advantage, with a tree height of 7 meters, the maximum range is 30 meters as shown in the diagram. Then, by reverse-engineering the formula for projectile motion…
He quickly wrote down several formulas on the draft paper.
The range R at height h is: R = (v² sin2θ)/g + (v cosθ) √((v sinθ)² + 2gh)/g
In planar flight (h=0), the maximum range R_max = v²/g
Given h=7m and R=30m, we can solve for the initial velocity v, and then substitute it into the plane formula... Hmm, the calculation result is approximately 24 meters.
After arriving at the final answer, Naruto was somewhat surprised; the question was unexpectedly simple.
