Please help with inelastic equations question!?
Two blocks are on a horizontal, frictionless surface. Block A is moving with an initial velocity of v0 toward block B, which is stationary, as shown above. The two blocks collide, stick together, and move off with a velocity of v0/3. Which block, if either, has the greater mass?
A. Block A B. Block B C. Neither; their masses are the same D. The answer can not be determined without knowing the mass of one of the blocks. Justify your answer.Please help me solve this problem. I am a bit confused.

Common sense suggests that if the resulting velocity is less than v0/2 then B is more massive.
You were taught the conservation of momentum?
(m_A)(v0) + 0 = (m_A + m_B)(v0/3)
m_B = 2 m_A
