Answer to Question #11661 in Mechanics | Relativity for keith

Question

2 runners initially standing next to each other run away from each other with the speed,v and after 360m they are 360m apart. what is the velocity?

Answer 1

The statement "after 360m they are 360m apart" is tautology, we'll appreciate it as a typo and understand as "after T seconds they are 360m apart". So,

2v·T = 360 ==> v = 360/(2T) = 180/T.
