Write down the formula that relates a particle's mass to its rest mass, and that which gives the particle's kinetic energy in terms of its mass. Explain what each symbol represents in [4 marks] [4 marks] Provide thorough arguments that lead to a law in special relativity called the law of [4 marks] [2 marks] i. the formulae. ii. Deduce from these or otherwise, Einstein's mass-energy equivalence law. iii. conservation of mass-energy. Give a formal statement of this law. Give a statement of the classical mechanics counterpart to this law. iv.
