Futsal is a sports modality that demands not only skill and physical conditioning, but also a deep knowledge of its rules and history for proper appreciation and practice. The sport, originated in the 1930s, has developed over the years and now features world championships that attract millions of spectators. Considering the development of futsal and its formalization as a competitive sport, answer: 1. Describe how changes in futsal rules over time influenced the style of play and team strategy. 2. Explain the importance of the main international futsal championships for player development and the popularization of the sport.

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.

Regular practice of sports has been widely encouraged as a way to promote health and well-being in people's lives. Based on the benefits and possible negative impacts of sports on the human body, explain why sports practice is healthy and mention two benefits and two negative impacts that may occur if sports are practiced inappropriately.

During the last practical class, the 3rd year high school students participated in an 'Ultimate Frisbee' tournament, an invasion sport that combines elements of American football, basketball, and soccer, requiring cooperation and team strategy to advance and score points. Considering the concepts of motion kinematics, where kinematics studies movement purely in terms of space and time, without considering the causes of that movement, the students observed that, to throw a frisbee, it is necessary to calculate the force and direction of the throw, taking into account the distance and wind speed. If a player wants to throw a frisbee, with a mass of 175 g, so that it travels a horizontal distance of 30 m and at a constant height of 2.5 m above the ground, disregarding air resistance and considering the local acceleration due to gravity as 9.8 m/s², what should be the initial velocity of the frisbee at the time of the throw? Additionally, suppose the player is able to apply a constant force to the frisbee during the throw. Calculate the initial velocity required to achieve this feat.
