Kinetic energy is the energy minus the rest energy, so that is 1.5 times the rest energy.
The speed follows from E = gamma m c^2 = gamma times the rest energy.
So, gamma = 2.5 ------->
v = 0.917 c
The speed follows from E = gamma m c^2 = gamma times the rest energy.
So, gamma = 2.5 ------->
v = 0.917 c
