How to find rest energy and kinetic energy of a ball?

Calculate the rest energy and the kinetic energy of:
a) A 100g ball travelling with the speed of 100m/s
b) An electron travelling at a speed of 0.999c.
Which one has greater rest energy? Which one has greater Kinetic energy? Don’t forget you are dealing with relativistic effects in at least one case.
