Two soccer players start from rest, 44 m apart. They run directly toward each other, both players accelerating. The first player's acceleration has a magnitude of 0.56 m/s². The second player's acceleration has a magnitude of 0.40 m/s². (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run?

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.
