Problem 68P
IP A particle has a kinetic energy equal to its rest energy, (a) What is the speed of this particle? (b) If the kinetic energy of this particle is doubled, does its speed increase by a more than, less than, or exactly a factor of 2? Explain. (c) Calculate the speed of a particle whose kinetic energy is twice its rest energy.
ANSWER:
Step 1 of 3:-
a)
Here, we have to find the speed of the particle.
Given that,
.
So, the speed of the particle must be 0.866 c.
