## Homework Statement

An 800 kg airplane traveling at a velocity of 120 m/s [30o N of E @ 20o above the horizon] collides with a stationary 1200 kg helicopter. If the velocity of the airplane after the collision is 65 m/s [40o N of E @ 60o above the horizon] what is the final velocity of the helicopter?

## Homework Equations

## The Attempt at a Solution

I don't understand what to do with the 20 degrees above the horizon part in both the parts.
