Question

(a) How much energy is required to accelerate a proton from rest
to 0.7*c*? (Rest mass = 938.27
MeV/*c*^{2}

(b) What is the momentum of the proton once it reaches this
speed? (Express your answer in units of MeV/*c*.)

(c) Would more, less, or the same amount of energy be required to accelerate an electron from rest to this speed?

Answer #1

An electron has a kinetic energy K of 1 MeV and is incident on a
proton at rest in the laboratory. Calculate the speed of the CMS
frame (The centre of mass, or centre of momentum, (CMS) frame is
that in which the sum of the momenta (i.e., the total momentum) of
all particles is zero) moving relative to the laboratory.
(a) Express the initial energies Ee, Ep and initial momenta pe,
pp of the electron and proton respectively (with...

Sun. If we were able to use 1.05 percent of this energy to
accelerate spaceships, then how many missions would be possible in
one year?

How much energy is required to accelerate a spaceship with a
rest mass of 124 metric tons to a speed of 0.565
c?
Hints:
In the acceleration process the energy we have is converted to the
kinetic energy of the spaceship. The classical kinetic energy of an
object is half of the mass multiplied by the square of the
velocity. What is the relativistic form of the kinetic energy?
