An electron of mass 9.11  1031 kg has a momentum of 2.06  1022 kgm/s. What is its speed?
 a. 0.800c
  b. 0.467c
  c. 0.602c
  d. It cannot have this momentum since it would require a speed greater than c.

Question 2

As the speed of an object increases, its relativistic momentum:
 a. stays the same as its classical momentum.
  b. does not change since momentum is a conserved quantity.
  c. increases less than it classical momentum.
  d. increases more than its classical momentum.
