This concludes the answers. If you need any more clarification, modification or correction, feel free to ask.

"Let y - axis be along north x - axis be along east from conservation of momentum, momentum before collision = momentum after collision. Therefore (18 g)(3.8m/s) i^cap + (30g) (2m/s)j^cap = (48g)v^rightarrow or, v^rightarrow = 1.425 m/s j^cap therefore speed
