Answer:
(a) The kinetic energy of a 1.10 g particle with a speed of 0.800 c can be calculated using the equation KE = (1/2)mv^2, where m is the mass of the particle and v is its velocity. In this case, the mass of the particle is 1.10 g and the velocity is 0.800 c, so the kinetic energy would be:
KE = (1/2) * (1.10 * 10^-3 kg) * (0.800 * 3 * 10^8 m/s)^2
(b) The rest energy of a particle is the energy it has when it is at rest. According to the equation E=mc^2, where E is the energy, m is the mass, and c is the speed of light. In this case, the rest energy would be:
E = (1.10 * 10^-3 kg) * (3 * 10^8 m/s)^2
(c) The total energy of a particle is the sum of its kinetic energy and rest energy. Thus,
Total energy= kinetic energy + rest energy
