At what value of u/v does the measured mass of a particle exceed its rest mass...
PHYS10121 a) A particle of rest mass m is travelling so that its total energy is 2mc. It collides with a stationary particle of rest mass m to form a new single particle. What is the 2. rest mass of the new particle? 9 marks] b) A photon hits an electron at rest and produces an electron-positron pair according to the reaction γ+ e- e" + e-+e+, what is the smallest possible photon energy for this to occur? You may...
A free particle, having rest mass Mo, is in vacuum and initially at rest in the lab frame S. It undergoes an acceleration under the action of a constant pure force F = (fo, fr, 0.0), where 0 c dt Find its 4-velocity U as a function of time and force. Sketch the graphs of the dependence of normalised 3-velocity 3 v/c and the Lorentz factor y(t) of the particle as a function of time t

(d) A particle of mass m is moving at a speed u and hits an identical particle that is siting at rest. What are their four-momenta in the center of mass frame (e) In the center of mass frame, the collision of the two particles in part (d) causes the particles to fuse and create a single particle with mass M »m (i.e. the two particle turn into one, the opposite of a decay) that is completely at rest in...
In the theory of relativity, the mass of a particle with velocity v ism=mo/(square root ((1- v^ 2)/ c^2))where mo is the mass of the particle at rest and ci s the speed of light. What happens as v goes to c?
An alpha particle collides with an oxygen nucleus, initially at rest. The alpha particle is scattered at an angle of 40.0° above its initial direction of motion, and the oxygen nucleus recoils at an angle of 45.0° below this initial direction. The final speed of the oxygen nucleus is 2.44×105m/s. (The mass of an alpha particle is 4.0 u, and the mass of an oxygen nucleus is 16 u.) What is the final speed of the alpha particle? Tries 0/10...

An alpha particle (mass = 4 u) has a head-on, elastic collision with a nucleus (mass = 158 u) that is initially at rest. What percentage of the kinetic energy of the alpha particle is transferred to the nucleus in the collision? %
An alpha particle collides with an oxygen nucleus, initially at rest. The alpha particle is scattered at an angle of 30.0° above its initial direction of motion, and the oxygen nucleus recoils at an angle of 27.0° below this initial direction. The final speed of the oxygen nucleus is 1.74×105m/s. (The mass of an alpha particle is 4.0 u, and the mass of an oxygen nucleus is 16 u.) What is the final speed of the alpha particle? What was...
An alpha particle collides with an oxygen nucleus, initially at rest. The alpha particle is scattered at an angle of 66.0° above its initial direction of motion, and the oxygen nucleus recoils at an angle of 42.0° below this initial direction.
