Lorentz factor γ = 100;
The quality of movement when M = γM0
C * = sqrt velocity V (1-1 of / gamma] 2 )
= 1/2 * E m 0 c 2 * c * (1-1 / c 2 )
If a person wants to accelerate to 60kg so much energy is required * 10 2.7 18 J
Energy of the Hiroshima bomb was 8.4X10 13 J, then we need 32,100 atomic bomb of energy
