A lithium nucleus has mass 5.1e-27 kg. If its speed |

| is 0.993c (that is, |

|/c = 0.993), what are the following values?

particle energy = 13.889e-9 J

rest energy = 4.59e-10 J

kinetic energy = 33.42e-9 J

Next an electric force acts on the lithium nucleus and does 2.4

10-9 J of work on the particle. Now what are the following values?

particle energy = ??

rest energy = 4.59e-10 J

kinetic energy = ??

I can't find the kinetic or particle energy for the new values.
