Mastering Physics: Work Required to Accelerate Relativistic Particles

Part A
How much work W must be done on a particle with a mass of m to accelerate it from rest to a speed of 0.909 {\it c}?
Express your answer as a multiple of mc^{2} to three significant figures.
ANSWER:

  W  = 1.399
  mc^2
Part B
How much work W must be done on a particle with a mass of m to accelerate it from a speed of 0.909 {\it c} to a speed of 0.990 {\it c}?
Express your answer as a multiple of mc^{2} to three significant figures.
ANSWER:

  W  = 4.690
  mc^2
