Three masses are moving along the x-axis. Their masses and velocities are m1 = m with v1 = v, m2 = 2m with v2 = 2v, and m3 = 3m with v3 = 3v (the minus sign indicating this velocity is in the negative x-direction). The three masses collide and stick together in a completely inelastic collision. What is the resultant velocity of the combined mass?
 a. 0, since their combined momentum is zero.
  b. 2v/3
  c. 14v/3
  d. v

 a. 6.4 m/s
  b. 33 m/s
  c. 29 m/s
  d. 0.62 m/s
