Finding initial velocity of two elementary particles

In summary, the process for finding the initial velocity of two elementary particles involves determining their masses and charges and using equations from classical mechanics and particle physics. Several factors, including mass, charge, and interactions, can affect the particles' velocities, and accuracy depends on precise measurements and data. The initial velocity is typically calculated using theoretical equations and experiments, but in some cases, specialized equipment can directly measure it. This information has various applications in particle physics, astrophysics, and engineering, such as understanding particle behavior and properties and improving technological systems.

I'm not sure how they got the extra (1/2)mv^2? My question is shown using pink font in the image below as well as my attempt.

There are two particles so you must consider the KE of both. (Note that in the figure both particles end up with zero final velocity.)
 

What is the process for finding the initial velocity of two elementary particles?

The process for finding the initial velocity of two elementary particles involves first determining the particles' masses and charges. Then, using equations from classical mechanics and particle physics, the initial velocities can be calculated based on the particles' interactions and any external forces acting on them.

What factors affect the initial velocity of two elementary particles?

The initial velocity of two elementary particles can be affected by several factors, including their masses, charges, and the strength of their interactions. External forces, such as electric or magnetic fields, can also impact the particles' velocities.

How accurate are calculations for the initial velocity of two elementary particles?

The accuracy of calculations for the initial velocity of two elementary particles depends on the precision of the measurements used for the particles' masses, charges, and interactions. Small measurement errors can lead to significant differences in calculated velocities, so it is important to use precise and accurate data.

Can the initial velocity of two elementary particles be measured directly?

In most cases, the initial velocity of two elementary particles cannot be measured directly. Instead, it is calculated using theoretical equations and data from experiments. However, in some cases, specialized equipment such as particle accelerators can be used to measure the velocities of particles directly.

What are some applications of knowing the initial velocity of two elementary particles?

Knowing the initial velocity of two elementary particles can have many applications in fields such as particle physics, astrophysics, and engineering. This information can be used to understand the behavior and interactions of particles, study the properties of matter, and design and improve technological systems that utilize particle accelerators or other high-energy particles.
