An electron and a proton are each accelerated through a potential difference of 10.0 million volts. a) What is the kinetic energy of the electron? What is the kinetic energy of the proton? b) Calculate the momentum (MeV/c) of the proton using classical equations. c) Calculate the momentum (MeV/c) of the proton using relati

### A proton is being accelerated along a straight line in a machine: Velocity, force, energy

A proton (m=1.67*10^-27kg) is being accelerated along a straight line at 3.6*10^5 m/sec ^2 in a machine. If the proton has an inital speed of 2.4*10^7 m/sec: What is the final velocity after traveling for 2 sec? What is the force acting on the proton? What is the increase in its kinectic energy?

### Relativistic Velocity and Kinetic Energy

Take the mass of a proton to be 1GeV (=1000MeV). Find the velocity (beta) of a proton whose kinetic energy is: 100 MeV 2 GeV 10 GeV 100 GeV According to Newtonian theory, the kinetic energy (mv^2/2) of a particle is c is equal to mc^2/2, which we now recognize as half of its rest energy. What is the actual (relativistic

### Rest Mass and Kinetic Energy

1. Can you express the rest mass of the electron in electron volts. 2. Compute the kinetic energy of a.) an electron b.) a proton traveling at .99c. 3. At what velocity (beta) does the kinetic energy of an electron equal its rest energy?

### To find the momentum of a particle with mass "m" so that the total energy of the particle is exactly 3 times its rest energy?

What must be the momentum of a particle with mass "m" so that the total energy of the particle is exactly 3 times its rest energy? The answer must be in terms of mc. Possible answers : a.) 3.45 mc b.) 2.83 mc c.) 5.17 mc d.) 0.045mc e.) 6.66 mc

### What Kinetic Energy Must this Beam Proton Have?

In the Tevatron accelerator/storage ring at the Fermi National Accelerator Laboratory, two beams of protons travel in opposite directions each with a total energy of 1 TeV and interact. Since these beams have momenta of equal magnitude but opposite direction, they interact in their center of momentum inertial frame. Hence s2 =

### Relativistic Collision

This is problem 12.34 from Griffiths' third edition of Electrodynamics: In the past, most experiments in particle physics involved stationary targets: one particle (usually a proton or an electron) was accelerated to a high energy E, and collided with a target particle at rest (Fig12.29a). Far higher relative energies are o

### Momentum and Relativistic Energy

Relativistic Energy and Momentum Learning Goal: To learn to calculate energy and momentum for relativistic particles and, from the relativistic equations, to find relations between a particle's energy and its momentum through its mass. The relativistic momentum and energy E of a particle with mass moving with velocity is g
