If a hypothetical particle, tepton, has a total energy of 3.0 GeV, calculate the speed (v) of the tepton (m = 9.11 x 10^-31 kg) in terms of the speed of light (c). Solve using the concepts of relativity.

Bob is located at a distance of x = 1242 m from the origin and when he observes light from two separate events. During Event "A", a flare gun fired at the origin (x = 0 m), and during Event "Q", another flare gun fired at x = 1850 m from the origin position. The light from both events reaches him simultaneously at 9.2 μs. Determine what the original time values are, considering when each of the flare guns were initially fired.

In a physics experiment, a particle that has a mass of 2.30 grams is accelerated to reach a velocity that is 70% of the speed of light (0.70c). Determine (i) the rest energy, (ii) the kinetic energy, and (iii) the total energy of this particular particle at this speed. Express your final answer using the most appropriate of the following prefixes: mega (M), giga (G), or tera (T).
