What does E0 = mc 2 describe?
a. The kinetic energy of an object of mass m moving at speed v.
b. The kinetic energy of an object of mass m moving at speed c.
c. The equivalence of mass and energy.
d. The form taken by Newton's second law at relativistic speeds.
e. The relativistic mass.

Question 2

The law of conservation of energy:
a. fails because energy increases too fast as the speed gets closer to c.
b. does not apply to the theory of special relativity.
c. applies to the theory of special relativity as long as the relativistic adjustment factor is correctly included.
d. applies to any given inertial system but not to others.
e. applies to the theory of special relativity in exactly the same form as it applies for small velocities.
