Consider massive gliders that slide friction-free along a horizontal air track. Glider A has a mass of 1 kg, a speed of 1 m/s, and collides with Glider B that has a mass of 5 kg and is at rest. If they stick upon collision, their speed after collision wil
 
  A) 1/4 m/s.
  B) 1/5 m/s.
  C) 1/6 m/s.
  D) 1 m/s.
  E) none of the above

Question 2

  A) 0 m/s.
  B) 1/2 m/s.
  C) 1/3 m/s.
  D) 1/6 m/s.
  E) 1.5 m/s.
