**Physics**

The compass in a plane indicates that the plane is heading due east, with an airspeed of 250 km/h (Vpa). A steady wind is blowing with a magnitude of 75km/h, which increases the velocity of the plane, relative to the ground. If the plane is going along a direction East 12 ...

**physics**

An airplane flies at airspeed (relative to the air) of 400km/h. The pilot wishes to fly due North (relative to the ground) but there is a 110km/h wind blowing Southwest (direction 225º clockwise from North). In what direction should the pilot head the plane (measured clockwise...

**Calculus 3**

Vectors The thrust of an airplane's engine produces a speed of 400 mph in still air. The wind velocity is given by <-20,30>. In what direction should the plane travel to fly due south? Give your answer as an angle from due south.
