A 2kg object moving 3m/s strikes a 1kg object initially at rest. Immediately after the collision, the 2kg object has a velocity of 1.5m/s directed 30° from its initial direction of motion. What is the x and y component of the velocity of the 1kg object just after the collision?

momentum is conserved. So after the reaction, you have 6kgm/s in x direction total.
of the two objects, then the y components of momentum must add to zero.
2kg*1.5*sin30+1kg*v'=0
solve for v'
