Calculate the reaction energy (Q value) for the reaction 7Li + 1H  4He + 4He, given the following masses:
  7Li: 7.016005 u
  1H: 1.007825 u
  4He: 4.002603 u
  (1 u = 931.5 MeV/c2)
 
  A) 15.37 MeV B) 17.35 MeV C) 17.53 MeV D) 13.57 MeV E) 13.35 MeV

Question 2

A 4.00-kg mass and a 9.00-kg mass are being held at rest against a compressed spring on a frictionless surface.
 
  When the masses are released, the 4.00-kg mass moves to the east with a speed of 2.00 m/s. What is the velocity of the 9.00-kg mass after the masses are released?
  A)
 
  2.00 m/s west
  B)
 
  0.888 m/s west
  C)
 
  0.500 m/s east
  D)
 
  4.50 m/s west
  E)
 
  0.500 m/s west
