Some channels show you the distance between the ball and the goal at freekicks. They also show the speed of the shot. On average a freekick is between 80 and 100km\h.
To find the speed of the ball, you can use the formula for momentum: momentum = mass x velocity. Rearrange the formula to find the velocity: velocity = momentum / mass. In this case, velocity = 1300 kg / 15 kg ≈ 86.67 m/s.
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
The ball's velocity changes to 0m/s and the boy's stays the same.
The velocity of the ball is 16 feet/sec when it is thrown upward.
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.

You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
To calculate the velocity of the ball just before it hits the ground, we can use the equation of motion: velocity = acceleration x time. The acceleration due to gravity is approximately 9.8 m/s^2. Given the time of 3.0 seconds, we can plug these values into the equation to find the velocity. Therefore, the velocity of the ball just before it hits the ground is 29.4 m/s.
The ball's velocity changes to 0m/s and the boy's stays the same.

The velocity of the ball is 16 feet/sec when it is thrown upward.
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
The acceleration of the ball is constant during any time interval where the velocity changes. At the moment the ball has zero velocity, the acceleration is the same as it was during the time interval when the velocity was changing. This can be calculated using the formula acceleration = change in velocity / change in time.
The fraction of force affecting the ball determines its acceleration and, consequently, its velocity. A higher fraction of force results in greater acceleration and a higher velocity, while a lower fraction results in less acceleration and a lower velocity.
The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
This is an old experiment. Neither. Both balls have the same velocity as gravity draws on them equally.
