A plane moves due east while the pilot points the plane somewhat south of east, toward a steady wind that blows to the northeast. The plane has velocity vecv_(PW) relative to the wind, with an airspeed (speed relative to the wind) of 215 km/h, directed at angle theta south of east. The wind has velocity vecv_(WG) is relative to the ground with speed 65.0 km/h, directed 20.0^@ cast of north. What is the magnitude of the velocity vec_(PG) of the plane relative to the ground, and what is theta ?

A person travelling eastward with a speed of 3 kmh^(-1) finds that wind seems to blow from north. On doubling his speed, the wind appears to flow from north-east. Find the magnitude of the actual velocity of the wind.

A person travelling east wards at the rate of 4 km h^(-1) finds that the wind seems to blow directl from the borth . On dubling ins speed, the wind appears to come from 45^@ north of west. Find the actual velocity of the wind.
