    Kinematic
In summary, in a kinematic equation, when a ball is thrown up and reaches its highest point, its velocity becomes zero. However, in the idealized description of the trajectory, the speed is zero instantaneously, meaning it is only for a brief moment. Due to limitations in measurement and air turbulence, there may be uncertainty in this value. Additionally, in the concept of infinite numbers, the idea of something being instantaneous may not be possible.

in a kinematic equation when you throw a ball up and it reaches its highest point its velocity becomes zero how long is it zero

In the idealized description of the trajectory, its speed is zero instantaneously, i.e. the duration of zero speed is itself zero! Ultimately, of course, your measurements have limited resolution and air turbulence will contribute to uncertainty.

or more simply, the velocity is always changing, it is never constant, so the velocity never stays at any value. It passes through the value zero at a certain time,but it does not stay that value.

in my thinking that there are infinite numbers so you could measure time presicely infinite so something being instantaneous would not be possible

"measure time precisely infinite" makes no sense. In any case, I would think "there are infinite numbers" would mean that you CAN have something "instantaneous"- that's basically what non-standard analysis is about.
 

1. What is "Throw Ball: Max Height & Velocity = 0"?

"Throw Ball: Max Height & Velocity = 0" is a mathematical concept that describes the motion of a thrown ball at its maximum height and when its velocity is equal to 0. It is often used in physics and sports to calculate the trajectory and speed of a thrown object.

2. How is the maximum height of a thrown ball calculated?

The maximum height of a thrown ball is calculated using the formula h = (v^2 * sin^2(theta)) / 2g, where v is the initial velocity of the ball, theta is the angle of projection, and g is the acceleration due to gravity. This formula assumes that air resistance is negligible.

3. What does it mean when the velocity of a thrown ball is equal to 0?

When the velocity of a thrown ball is equal to 0, it means that the ball has reached its maximum height and is momentarily at rest before falling back down. This occurs at the peak of the ball's trajectory and is also known as the ball's apex.

4. Can a thrown ball have a maximum height and velocity of 0 at the same time?

Yes, a thrown ball can reach its maximum height and have a velocity of 0 at the same time. This happens at the peak of the ball's trajectory when it is momentarily at rest before falling back down.

5. How is "Throw Ball: Max Height & Velocity = 0" used in real-life applications?

"Throw Ball: Max Height & Velocity = 0" is used in various real-life applications, such as in sports like baseball and football to analyze the trajectory and speed of a thrown ball. It is also used in physics to study the motion of objects in free fall and in engineering to calculate the launch trajectory of projectiles.
