Two masses m1 and m2 are traveling in the direction of each other. The speed of m1 is v1 and oriented along the positive x-direction, while

Two masses m1 and m2 are traveling in the direction of each other. The speed of m1 is v1 and oriented along the positive x-direction, while that of m2 is v2 and oriented along the negative x-direction. The masses are such that m1 = m2/10.
A) If the two masses stick together, in what direction do they travel after they impact?
i. to the left
ii. not enough information
iii. to the right
iv. they will stop at the point where they collide
