An η meson, whose rest energy is 548 MeV, is moving in the Lab frame with a total energy of 685 MeV in the +x-direction. It decays into two photons a) What is the momentum of the n before the decay? b) What is the velocity of the n before the decay? c) Given that one of the photons is detected going in the +x-direction (this is one of many possible scenarios), find its energy and the energy and direction...

An electron (rest mass me) of
energy E makes a head-on collision with a positron (positron is
electron’s antiparticle, it has the same mass as electron, but
opposite charge) In collision the two particles annihilate each
other and are replaces by two photons (γ rays) of equal energy,
each traveling at equal angles θ with electron’s direction of
motion. Find 1. The energy of each photon. 2. The momentum p of
each photon. 3. The angle θ.

1) Imagine you have the following hypothetical "collision(s)". A massive particle (A), with mass, MA, is at rest. It then decays into three particles, B (of mass, mg). C and D (both massless, with the same magnitude of momentum, 110, and energy, E.). a) (5 pnts, Write the general conservation of 4-momentum relation for this situation in terms of 4-vectors). For parts b-c), assume that particle B is produced at rest: Before Ater: b) (10...

6. A playground merry-go-round, i.e., a horizontal disc of radius 3 m that can rotate about a vertical axis through its center, is rotating at an angular speed 1/s (measured, as usual, in terms of radians). The moment of inertia of the merry-go-round with respect to that axis is 3000 kg m? A student of mass 80 kg is standing at the center of the merry-go-round. The student now walks outward...
