    Two Particles On A Collision Course

    A and B are two points on a straight line. How far apart they are, depends of how this question requires them to be.

    Two particles C and D starting from points A and B respectively are on collision course. The velocity of each of the particles is the same. It is 75% the speed of light.

    What is the relative velocity of one particle with respect to the other?

    Incidentally the speed of light is 186284 miles per second.

    Imagine a situation in which two cars are on a direct collision course towards each other, both travelling at 50 mph. What is the velocity of the cars relative to each other? I.e. if you were sitting in the first car, how fast would the second car... read more
