A body of mass 8kg moving with a velocity of 10m/s collides with another body of mass 6kg moving in the opposite direction with a velocity of 50m/s.determine their common velocity in the direction of A after collision

Answer 1

I guess they stick together.

8*10 - 6*50 = (6+8) v

-220 = 14 v

v = -15.7 m/s

Answer 2

8*10 + 6*50 = (8+6)v
80+300 = 14v
380=14v
v=27.14m/s
