A device that is used to measure wind speed is called an anemometer. When it measures the wind on a moving object the measured value is called the apparent wind. A boat carries onboard an anemometer and measures the apparent wind velocity as 30 km/h, coming from an apparent direction of 15◦ east of north. At that time the boat is traveling at 16 km/h at 55◦ east of north relative to the ground. What is the magnitude and direction of the velocity of the wind relative to the ground? For full credit, you must draw a full, labelled vector addition diagram representing this situation.

An airplane’s speed relative to the air is 220 km/h. A GPS+compass device in the cockpit, however, indicates that the actual velocity of the plane with respect to the ground is 140 km/h due north. Assuming that the air is moving in a wind towards the east, what is the wind speed?

Suppose that a wind is blowing from the direction N45°W at a speed
of 50 km/h. (This means that the direction from which the wind
blows is 45° west of the northerly direction.) A pilot is steering
a plane in the direction N60°E at an airspeed (speed in still air)
of 100 km/h. The true course, or track, of the
plane is the direction of the resultant of the velocity vectors...

While the wind is blowing due East at 87 km/hr relative to the ground, a jet travels due North at 562 km/hr relative to the wind (the air). Obviously, the wind will push the jet eastward and throw the jet off course. What is the velocity of the jet relative to the ground? Before you do any calculations, make sure that you draw a diagram that shows reference frames S and S', Also, make sure that you label the velocities...
