A car is about to exit through a ramp traveling at a speed of 60 km/h. It starts decelerating uniformly as it reaches point A because it has to decrease its speed to 40 km/h before entering the ramp at B. From point B, it then decelerates by 0.2 m/s2 until it reaches point C, after which it travels at a constant speed.

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
