Two particles collide, one of them initially being at rest. Is it possible for both particles to be at rest after the collision?
 a. If the collision is perfectly inelastic, then this happens.
  b. If the collision is elastic, then this happens.
  c. This can happen sometimes if the more massive particle was at rest.
  d. No.

Question 2

An electron and a proton are each released from rest in the same uniform electric field. The electron moves a distance delectron and the proton moves a distance dproton as each particle's kinetic energy increases by 1.6 eV. How do delectron and dproton compare?
 a. delectron > dproton
  b. delectron = dproton
  c. delectron < dproton
  d. The answer depends on the direction of the electric field.
