During a soccer match, a player kicks a ball weighing 0.4 kg with a speed of 20 m/s towards the goal. Considering that momentum is the product of an object's mass and its velocity, answer: a) What is the momentum of the ball just after the kick? b) If a goalkeeper manages to stop the ball in 0.5s, what is the average force he applies to the ball to stop its movement? c) If the ball reaches the goalkeeper at a distance of 30m from the player who kicked it, what is the magnitude of the average velocity of the ball during the journey?Answer sheet:
