A jet airplane flying from Darwin, Australia, has an airspeed of 260 m/s in a direction 5.0º south of west. It is in thejet stream, which is blowing at 35.0 m/s in a direction 15ºsouth of east. What is the velocity of the airplane relative tothe Earth? (b) Discuss whether your answers are consistentwith your expectations for the effect of the wind on the plane’spath.

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
