(Originais Teachy 2024) - Question Hard of Physical Education

During an interdisciplinary class, 7th-grade students are learning about the sport of darts in the context of physics mechanics and geometry mathematics. Considering a dartboard divided into 20 different scoring segments, where each segment has an associated score and there are also rings that multiply this score, a student throws a dart that, after a parabolic trajectory, hits the target at a precise point. The teacher, taking advantage of the situation, asks the students to calculate the exact distance between the throwing point and the center of the target, knowing that the dart hit the highest scoring segment of the target and considering the standard rules of the game of darts that establish that the central segment of the target has the highest scoring value and the target is fixed at a height that allows the dart's trajectory to be modeled by a parabola. Additionally, the force and angle of dart throwing are provided as functions of trigonometric variables, and any air effects are disregarded. Based on this information, determine the exact distance between the throwing point and the center of the target.
a.
The exact distance between the throwing point and the center of the target is 2 times the radius of the central segment.
b.
The exact distance between the throwing point and the center of the target is 3 times the radius of the central segment.
c.
The exact distance between the throwing point and the center of the target is 6 times the radius of the central segment.
d.
The exact distance between the throwing point and the center of the target is 4 times the radius of the central segment.
e.
The exact distance between the throwing point and the center of the target is equal to the radius of the central segment.

Did you know that many games and activities we love have origins in the cultures of indigenous and African peoples? These games are very important because they helped shape the culture of our country, Brazil. By observing the games you enjoy playing the most at school or at home, and thinking about what we have learned from indigenous and African cultures, how do you think these games may have come from these peoples and contributed to our society? Share your thoughts and give an example of how a game could have this origin.

Volleyball, created in the late 19th century by William G. Morgan in the United States, quickly spread around the world, becoming one of the most popular sports in terms of participation and spectators. With its complex strategies, varied game dynamics, and demand for specific physical and technical skills, volleyball is a sport rich in details. In a volleyball match, reading the game is fundamental to anticipate and react to opponents' actions, and the players' positions on the court play a crucial role in this aspect. Consider a situation where a team is devising its game strategy to overcome a notoriously strong opponent in blocking. The coach, knowing well the capabilities of his athletes, decides to position the middle blocker, who has good blocking ability, in a position that historically offers a tactical advantage in direct confrontation with the opposing opposite hitter, who accelerates his jumping ability. Analyzing the interaction between the laws of physics and the biomechanics of the human body, determine the ideal position of the middle blocker in relation to the net at the moment when the opposing attacker is most likely to touch the ball to overcome the block, considering that both players are in ideal conditions to execute their actions and disregarding any effects of wind or other external variables.

As a sports scientist, you are tasked with creating a new game that combines elements of net sports like volleyball and wall sports like climbing. Describe how this game would be, including the basic rules, how players can score points, what is needed to play, and the importance of each element (net, ball, wall, safety equipment) for the game to function. Also explain what the ultimate goal of the game is and how players can work together as a team to achieve it.
