then speeds up with constant A passenger plane is travelling down the runway with a speed of 20 acceleration for 59 s over 2.4 km. We want to find the final velocity of the plane at the moment of take- off. Which kinematic formula would be most useful to solve for the target unknown? Assume the initial direction of travel is the positive direction. Choose 1 answer: B D v=v0+at - (+) Az- - + 2aAx but + 2 t Stuck? Review related articles/videos or use a hint. Report a problem

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.
