Answer:

B

Step-by-step explanation:

This looks like a momentum question. It also looks like there is no horizontal acceleration.

Momentum before Momentum after

m1vo (m1 + m2)*vo/3 multiply through by 3

3 m1*vo m1* vo + m2*vo subtract m1*vo from both sides

3m1*vo - m1*vo m2*vo

2m1*vo m2*vo Divide by vo

2m1 = m2

Conclusion: It takes 2 m1's to equal 1 m2.

B is the answer.
