Answer:
4.999 × 10⁴ MeV
Explanation:
Kinetic energy is related to the rest energy by the Lorentz transformation equation as shown below.
Kinetic energy in the lab frame K= ( γ -1 ) Eo
The Lorentz constant γ = [tex]1/\sqrt{1-v^2/c^2}[/tex]
So γ = [tex]1/\sqrt{1- (0.99217 c)^2/c^2}[/tex]= 8.0067
⇒ K = (8.0067-1)(7134) = 49986 MeV
=49,999 MeV ( 4 significant figures)
