Football, as a global socio-sporting phenomenon, has rules that not only regulate the game itself, but also reflect cultural and social values of different communities. Considering the complexity and historical richness of the sport, knowledge about its rules and evolution is essential for a deeper appreciation of the game. As sports philosopher Johan H. Evenepoel points out, 'Sports rules are, above all, cultural rules that reflect the history and values of a particular community.' Based on this statement, write a text where you: 1) Explain the importance of rules in football and how they relate to cultural and historical aspects of the sport; 2) Discuss the evolution of a specific rule in football over time, highlighting how this change reflected the needs or values of the society at that time.

Have you ever heard that dance can be considered a Historical Heritage? Research about a dance that is considered a historical heritage in our country. Describe the chosen dance, explain why it is considered a historical heritage, and how it contributes to physical activities and Brazilian culture.

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.

The practice of hockey extends across different cultures around the world, being adapted in their styles and rules for ice rinks, grass fields, and even aquatic environments. Aspects such as technical skills, game strategy, and understanding of the rules are fundamental for the players' performance. In the context of an ice hockey match, the contact force between the stick and the puck, combined with the speed of the movement, determine the trajectory and the kinetic energy involved in the athletes' actions. Consider a player who applies a tangential force of 250 N using his hockey stick at an angle of 30° relative to the horizontal plane when making a pass. Disregarding the effects of air resistance and considering that the puck has a mass of 150 g, determine the acceleration of the puck at the moment of the pass and the component of the force that contributes to the change in kinetic energy of the puck in the direction of movement.
