A 1000-kg spacecraft passes you at 1/5 the speed of light, What is its relativistic energy?
Relativistic energy, E = mc^2/ sqrt(1 - (v/c) ^2)
E = (1000 x (3 x 10^8)^2)/ sqrt(1 - 0.04)
E = 9.19 x 10^19 J

Light speed and classical physics. a. How much energy would it take to accelerate an electron to light speed according to classical (non-relativistic) physics? b. With this energy, what is its actual (relativistic) speed?
When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...
5. The relativistic corrections to the energy of a particle can be estimated by applying a fictitious "external potential” V = -p4/8m'c>, where p is the momentum of the particle, m is its mass, and c is the ħ d speed of light. Replacing p with its operator (p= ), the corresponding operator for the "external potential" is = - a . Is the ground state wavefunction of the particle in a box ( sin (**)) an eigenfunction of the...
3) A 40,00o kg spacecraft travels to a planet that is 1o light-years away. The one-way trip takes 5 years in the reference system of the spacecraft. The spacecraft uses a radio transmitter with a wavelength of 8.o cm to communicate with earth. What are the wavelength, frequency, and energy of the radio photons as observed back on earth?
