Final answer:
The defender's action would be penalized with a penalty kick. The displacement-time graph of the soccer ball would show a linear relationship. Lastly, sharing the same viewpoint as a friend during a soccer game indicates you share the same reference frame.
Step-by-step explanation:
The question involves understanding the rules of soccer and applying the laws of physics to different scenarios, specifically projectile motion and displacement over time in sports contexts. If Team B's keeper leaves the goal in pursuit of the ball and a defender deliberately handles the ball to stop a goal, the referee would award a penalty kick to Team A for the handling offense. However, when considering the physics aspect of displacement over time, if a defender kicks the ball back to their goalie and it stops, and then the goalie sends it back, the displacement-time graph would show a linear relationship both ways, with the displacement reaching zero when the ball stops momentarily.
As for the ability of a goalkeeper kicking the soccer ball into the opponent's goal without it touching the ground over a distance of about 95 m with a speed of 30 m/s, this involves calculating the projectile motion which is determined by the initial velocity, angle of projection, and acceleration due to gravity. For the basketball question, finding the angle above the horizontal involves solving a projectile motion problem, taking into account the initial speed, the distance to the basket, the release height, and the height of the basket.
The pool game scenario with Jose Sharco is a playful take on one's understanding of the physical world; a pool shot requires a physical interaction with the ball, and it cannot be influenced purely by mental concentration. Lastly, watching a soccer game from the same viewpoint would mean you both share the same reference frame for observing the game.
