At the start of a soccer game, the soccer ball, a spherical leather football, is 27 to 28 inches (69-71 cm) in circumference and 14 to 16 ounces (396-454 grams) in mass. The goalkeeper is the only player that is allowed to handle the ball. The remaining players are permitted kick, dribble, and pass the ball with their feet, head, and trunk.
The average mass of a soccer ball depends on the size and material of the soccer ball used. The average mass is 0.43 kg.

will explain why. The mass of a professional soccer ball is about m = 0.4 kg. The velocity of the ball equals the velocity of the leg multiplied by the fraction of the mass of the leg over the total mass of the leg and the ball, multiplied by 1 + e. Suppose the mass of the leg for a small person (who
Mass and Acceleration. When an object changes its speed, it’s called acceleration. The larger the change in speed, the larger the acceleration. We can also predict how much the soccer ball will accelerate during the kick if we know something about the soccer ball: its mass. Mass is the amount of matter in an object.

Example 8.3 Kicking a soccer ball soccer ball has a mass of 0.40 kg. Initially it is moving to the left at 20 m/s but then it is kicked. After the kick it is moving at 45 ° upward and to the right with speed 30 m/s (Fig. 8.7a).
A stationary soccer ball of mass m = 0.74 kg is kicked with a constant force of F = 23 N. The player's foot is in contact with the ball for t = 0.17 s.. Part (a) Write an expression for the speed of the ball, v i, as it leaves the player's foot.
