The air is moving at 70km/hr at 15 degrees West of South relative to the Earth.  The plane has a speed relative to the air of 200km/hr.

 

  • In which direction should you point the plane so that it will head due East according to people on the Earth? (I’m looking for an angle value with direction)

 

  • In a separate DVD selection, the plane of mass 2400kg travels at 115km/hr through still air due West.  The plane then encounters a mysterious monster of mass 1350kg traveling at 160km/hr due East.  The monster is stuck to the plane after they collide.  At what speed and in which direction is the plane+monster traveling the instant after the collision?  Ignore gravity during the collision and assume that there is no wind anymore.
