(9) An unstable particle at rest breaks into two fragments of unequal mass. The mass of the lighter fragment is 1.75 MeV/c2 and that of the heavier particle is 3.50 MeV/c2. The lighter fragment has a speed of 0.956 c after the breakup.
(i) What is the speed of the heavier fragment? Express your answer as a fraction of c, the way the speed of the lighter fragment is expressed above.
(ii) What is the kinetic energy of the lighter fragment, in electron volts (eV)?
(iii) What is the speed of the lighter fragment as seen by the heavier fragment? Express your answer as a fraction of c.
