Two protons fly in different directions and collide. They both have a total energy of 1.5 GeV, but have the opposite direction so that the mass center is at rest for an observer in the laboratory.
What are the protones velocities seen from the laboratory?

3. (10 pts) High energy particle accelerators convert part of the energy of colliding particles into the masses of particles produced in the collisions. Consider a collision of two protons that produces two charged kaons. The mass of the proton is mp- 938.3 MeV/c2, and the mass of each kaon is mK 493.7 MeV/c2. The reaction is a) The total energy (kinetic energy and rest energy) and total momentum is conserved. Suppose one of the protons is at rest in...

A muon and an antimuon are moving in opposite directions with velocities of -0.4 c and 0.4 c, respectively. When they collide, they can annihilate each other and turn into two photons. Both muon and antimuon have a mass of 105.66 MeV/c2. What is the total energy before the collision? What is the energy of each photon? What is the wavelength of each photon?

A muon and an antimuon are moving in opposite directions with velocities of -0.9 c and 0.9 c, respectively. When they collide, they can annihilate each other and turn into two identical photons. Both muon and antimuon have a mass of 105.66 MeV/c2. What is the total energy before the collision? What is the energy of each photon? What is the wavelength of each photon?

Suppose in a reference frame S, two objects collide elastically. Particle 1 of mass m1 = 2m is initally at rest, and particle 2 of mass m2 = m is moving with an initial velocity of u2i = −0.75c (negative means moving in the −x direction). The two particles collide elastically. Using classical momentum and energy conservation, an observer in frame S calculates the velocities after collision to be u1f = −0.5c, u2f = 0.25c. (a) Verify that the kinetic...

two balls that are set to be collide elastically, give these two balls specific masses and initial velocity. The balls cannot have the same mass, and they must be moving in both the x- and y-directions. These are the data: Mass for ball 1=3kg Mass for ball 2=5kg Initial velocity ball 1=1.50 Initial velocity ball 2=2.0 Use Conservation of Momentum in x and y, as well as Conservation of Energy, to determine the final velocities of the balls after the...
