A proton has a kinetic energy of 128MeV What is the speed of this electron? (as a fraction of c)

Derive an expression for E using the attached equation (Lorentz Force Law), and calculate a predicted value for E in N/C if a particle had v = 40 m/s, q = -0.001 C, m = 0.3 ⨉ 10 -3 kg, and B = 0.6 T.

Six identical particles have a speed 2m/s except for the last ( which is the seventh) particle which has a speed of 4m/s. What is the vavg of these particles?

6. A particle has a speed of 96% of the speed of light and a mass of 1u. The particle is unstable and its lifetime is 150 ns. It passes through a room where we stand and observe.   (a) How long do we think the lifetime of the particle is?   (b) The room is 10 m long, but how far does the particle feel as it passes?  (c) How much of the particle's total energy is rest mass?

What is the velocity of a proton with a kinetic energy of 3.4 eV. Give your answers in 105 m/s with 3 decimal places.

4. In a colliding beam apparatus, two beams of protons are aimed at each other. The first proton moves with a speed of 0.70c to the right; the second moves with a speed of 0.90c to the left. Both speeds are measured relative to the laboratory frame of reference. What is the speed of the second proton relative to that of the first? oofl

Consider a proton moving with speed = 0.94 c. (c is the speed of light.) What is the kinetic energy, in MeV? (in MeV) OA: 1160 OB: 1449 OC: 1812 OD: 2265 OE: 2831 OF: 3539 OG: 4423 OH: 5529

What is the speed, in m/s, of a proton after being accelerated from rest through a 50 x 106 V potential difference?

How much work must be done to increase the speed of an electron from rest to (a) 0.436c, (b) 0.967c, and (c) 0.9961c?

Particle track detectors are used to measure the speed of particles if the lifetime of the particle is known. Particle X has a lifetime of 256.2 ps. These particles are created in an experiment inside the detector by a given reaction. The particles leave 21.6 cm long tracks on average before they decay into other particles not observable by the detector.What is the average speed of the particles in terms of the speed of light?
