a(n) 6kg object moving with a speed of 8.3 m/s collides with a(n) 18kg object moving with a velocity of 10 m/s in a direction 23(degrees) from the initial direction of motion of the 6kg object.
What is the speed of the two objects after the collision if they remain stuck together?
(answer in units of m/s)

drwls,
This is a conservation of momentum problem. You must apply it in two perpendicular directions. Please show your work. Further assistance will be provided if needed.
