   Thats life, you get back you insert!   
      
   Your kinetic energy is 2 m c^2, your mass is 4 m so by Newton you have   
   1/2 *4m *c^2 = 2 m c^2.   
      
   This is completly independent of the numerical value of c. We only have   
   to assume the approximate Newtonian formula   
      
   E = mc^2 + 1/2 m v^2 -.+.-   
      
   In fact the total energy including rest energy mc^2 is   
      
   E = mc^2 /sqrt(1-v^2/c^2)   
      
   going to infinity as v->c.   
      
   The kinetic energy as the difference between total energy and rest energy   
      
   T = E - m c^2 = mc^2 /sqrt(1-v^2/c^2) -mc^2 = 4 m c^2   
      
   yields sligthly less than c   
      
   1-v^2/c^2 =1/5   
   v = c 2/sqrt(5)
