In the games, the team members who entered the finals in 100m and 200m were divided into finals acco

The 100m and 200m finals are generally arranged according to the results of the semi-finals. The best results in the semi-finals were ranked in four. The second place is in the fifth lane, the third place is in the third lane, the fourth place is in the sixth lane, the fifth place is in the second lane, the sixth place is in the seventh lane, the seventh place is in the first lane, and the eighth place is in the eighth lane.

There are also some large-scale individual competitions where the final is decided by another draw. I don't know if I'm satisfied.

The 100m and 200m finals are arranged in relation to the athlete's performance in the semi-finals. The specific arrangements are as follows:

1.The athlete with the best score in the semi-finals is in lane four.

2.The second-best athlete is on lane five.

3.The third-best athlete is on lane three.

4.The fourth-best athlete is on lane six.

5.The fifth-best athlete is on the second lane.

6.The sixth-best athlete is on lane seven.

7.The seventh-best athlete is on the first plate.

8.The athlete with the eighth best finish is on lane eight.

This arrangement method is mainly based on the performance of athletes in the semi-finals to determine their passes in the finals, so as to ensure the principle of fair play.

The rules of athletics stipulate that the top four athletes or teams are selected and decided by lot. Select Perigo.

Five or six athletes or teams will be decided by lot. The bottom two athletes or teams are selected and decided by lot.

Tracks are divided according to each other place in the rankings.

Summary. The 100-meter race is an outdoor track and field sprint and one of the most popular and well-known track and field events. This is a sprint track event and must be started with a starting gear.

In the modern Olympic Games, the men's 100m has been an official event since 1896, while the women's 100m has been an official event since 1928. The person who won the 100-meter Olympic title is often referred to as "the fastest man in the world". The world record in the men's 100m was set by Jamaican athlete Usain Bolt at the World Athletics Championships in Berlin, and the women's world record was set by American athlete Florence Griffith-Joyna in the rematch of the US Olympic Trials.

Dear, hello, I am happy to serve you, the 100-meter preliminaries results smile and bring the first place athlete in the rematch of the ambush track may be the last two, this is not a side to determine this is arranged by the event Oh <>

Summary. Dear, I'm glad to answer for you! In the 200 meters, athletes finish in 1 minute and 40 seconds, and they rate the speed as 2 meters and seconds. 200 meters divided by 100 seconds equals 2 meters per second, and the average speed of this athlete is 2 meters per second.

Extended Related: Considerations for AthletesPreventing Injuries: Before engaging in any physical activity, make sure you have warmed up and stretched adequately.

In addition, it is important to wear appropriate sports shoes and equipment. Arrange your training plan reasonably: Avoid overtraining and increase the amount of exercise immediately to avoid injuries and other physical problems.

Eat a balanced diet: A good nutritious diet is essential for both good health and athletic performance. Make sure your diet includes enough protein, carbohydrates, healthy fats, and enough water.

Get enough rest: Sleep is essential for your body's recovery and repair. Please make sure you get enough sleep each night and arrange the necessary rest.

Emergency Handling Skills: In an emergency, such as an injury or sudden illness, it is important to learn basic first aid knowledge and handling skills.

According to the data in the table, the time taken by the soldiers in 0 20m, 20 80m, and 80 100m is , and ; Then the average speed of the soldier in different road sections: V1s

a. From the question, it is known that the athlete has run 4 laps, and the total displacement is zero, so the average speed is zero, and A is wrong;

b. The acceleration is large, the speed is not necessarily large, and the speed is not necessarily large, and the acceleration is wrong;

c. The displacement of all athletes is zero, and the distance is 1200m, which is equal, and C is correct;

d. The faster the speed changes in a certain moment during the starting process, the faster the athlete's acceleration must be, d is correct;

Selection: CD

9:20:40 refers to the moment when the athlete stands on the track; 9:20:50 refers to the time of departure; 9:25:28 is the moment to reach the finish line; 4 minutes and 38 seconds refers to the time to complete the race;

Therefore, the time indicated in the description is 4 minutes and 38 seconds;

Therefore, b

(1) The time of Wang Xiaobing within 0 20m is: t1=, and the average velocity of Wang Xiaobing within 0 20m: v1=s

t=20m The time of Wang Xiaobing in 20 80m is: t2=, and the average velocity of Wang Xiaobing in 20 80m: v2=st=80m?20m

The time of Wang Xiaobing in 80 100m is: t3=, and the average velocity of Wang Xiaobing in 80 100m: v3=st=100m?80mm

Wang Xiaobing's speed in the range of 0 20m, 20 80m, and 80 100m is different, and the speed is different, so Wang Xiaobing carries out linear motion with variable speed

2) The three athletes pass the same distance, the less time, the faster the movement, Zhou Wei takes the least time, Zhou Wei moves the fastest, and Zhou Wei is the champion

Zhou Wei's average speed: v=s

t=100m

So the answer is: (1);; Gear shift; (2) Zhou Wei;

(625-1) 4=156 (times);

A: It takes 156 races to determine the winner

So the answer is: 156
