About ten minutes later, Kiko watched as Jiang Zifan finished his meal and wrote down a formula on a piece of paper on the dining table. F=2mvωsinφ。
"What is this?" Kiko was puzzled.
"Deflective force of the tiles!" Jiang Zifan said," Due to the Earth's autobiography, objects will have a certain degree of sideways movement when they are moving in a straight line for a long distance. They will deviate to the right in the northern hemisphere and to the left in the southern hemisphere.”
"The longer the distance of movement, the greater the horizontal deviation!”
" m represents mass, V represents speed, Omega represents the angular velocity of the Earth's rotation, and then is the latitude of New York.”
Jiang Zifan looked at the confused KikO and smiled." You have to know that just because a body was found doesn't mean that it just happened to arrive at the location where it was found. It might have been there for a long time. "Moreover, you have to know that it takes time for a person to die from having their kidney removed. The time given by the police was the time of her death, not the time of the crime.”
"When the police investigate the crime scene, they will patrol the vicinity. If the crime scene is near the river bank, then the police will discover it at that time. If the crime scene was on the right side of the river, then the body would not have floated far before it was washed to the shore by the river. Therefore, I deduced that the crime scene was on the left side of the river!”
“Oh，mygod!”Kiko looked at Jiang Zifan with a hint of shock in his eyes. He did not expect that this fellow who was ranked last among the group of detectives would actually be ahead of Qin Feng in this step.
"According to the calculations, the horizontal acceleration of the victim caused by the gravitational force is 7.6 cm/s.”Jiang Zifan glanced at KIKO, who was listening, and continued teaching.
"The width of the Manhattan section of the Hadson River is about 1.2 kilometers.”Jiang Zifan turned on his iPad and showed the map to Kiko." But the location where the body was found, the width of the river is 1.6 kilometers, which means that the victim floated in the water for more than 20,000 seconds before getting there. The speed of the current is 0.4 meters per second, so we have to swim at least 8.42 kilometers upstream to find where she fell into the water!”
"8.42 kilometers?" Kiko took a look at the map." Washington Park is 8.42 kilometers away.”
"The crime scene is nearby!”Jiang Zifan put away his pen and paper and smiled." And it's by the water. Coincidentally, there's an abandoned shipyard near Lincoln Center!”
In the plot, Qin Feng's deduction of the crime location was wrong. It was Song Yi who brought them to the correct location.
Then where did Qin Feng go wrong?
The time he calculated was the time of the victim's death and the time when he was found.
According to the forensic doctor, the time of death of the victim had a two-hour margin of error.
Even though Qin Feng used the largest range, he still made a mistake in his calculations. He thought that the deceased was thrown into the water after he breathed his last. In fact, he fell into the water and floated for a while before dying.
Therefore, Qin Feng did not consider the time when the other party fell into the water and died.
That was why his calculation of the location was worse than Song Yi's.
Song Yi was probably laughing in his heart at that time! The second-ranked detective didn't even know this?
Jiang Zifan analyzed it from the perspective of an engineer and a geography expert, so he calculated the correct location.
After listening to Jiang Zifan's explanation, KikO was in disbelief." Brother, aren't you studying architecture?”
"What is this now?" " Is it the God of geography?" she asked.
"Haha!" Jiang Zifan smiled and explained to KAKO," The tilting force of the tiles is also one of the factors to consider when building a highway!”
"That's because, whether it's in China or the United States, for every thousand meters a car travels, it's about one meter cheaper to the right. Therefore, the highway was usually not particularly straight. There would be a certain degree of curvature.”
Speaking of this, Jiang Zifan explained to KAKO," This is to prevent the driver from being too relaxed because the road is too straight. Sometimes, the road is too straight and it is easy to get into an accident.”
Kiko nodded, deep in thought. Meanwhile, Jiang Zifan was looking for Feng Shui knowledge on his phone, especially pictures of the five elements.
After a while, a strange piece of news appeared on the TV in the restaurant. All the customers in the restaurant laughed.
"What's wrong?" Jiang Zifan raised his head and suddenly saw Qin Feng and Tang Ren running naked on TV…
"Sigh, they're in trouble!" KikO said.
"What do you mean?" Jiang Zifan asked.
"They escaped with the wanted criminals, so they will definitely be wanted as well.”
"Looks like it's impossible to count on them to catch the real murderer!”" It's a pity," Kiko said." The arrest warrant of the NYPD will cause them a lot of trouble in solving the case. Coupled with the pursuit of the underworld, it's even more impossible."”
