E=(gamma)mc^2
where E is total energy (rest mass energy plus kinetic)
Gamma is the lorentz factor (1/sqrt(1-v^2/c^2))
m is mass
c is speed of light in vaccum
v is object velocity
As a very crude estimate to answer the OP, if you have E=10^69 J then the velocity of your object is on the order of 10^-60 m/s slower than the speed of light.
