During an athletics competition, a group of 2nd-year high school students decided to investigate the performance in track and field sports and its relation to the laws of physics. In particular, they focused on high jump and shot put. In high jump, they observed that an athlete, weighing 70 kg, reached a height of 1.90 m in his best attempt, while in shot put, another athlete, with the same weight, threw a 7.26 kg weight a distance of 15.00 m. Considering that the acceleration due to gravity is approximately 9.81 m/s² and that there was no significant air influence on the observed movements, calculate the mechanical energy involved in the movement of each athlete in their respective activities. Relate these values to the necessary muscular power and discuss how understanding these quantities can be applied to optimize the athletes' performance in track and field sports.

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.

With the exponential growth of the electronic gaming industry, it has become common to hold championships and competitions that bring together thousands of players and spectators. These events demand not only technical skills from the competitors, but also strategies and teamwork. Considering this context, discuss the role of electronic games in contemporary culture, analyzing how the practice and observation of these games can contribute to the development of social and cognitive skills of the players. Additionally, evaluate the positive and negative impacts that the inherent competitiveness of electronic games can have on the formation of individuals and the social dynamics of the groups that participate in these practices.

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.
