Relativity According to the Theory of Relativity, the length L of an object is a function of its velocity v with respect to an observer. For an object whose length at rest is 10 m, the func- tion is given by L(v) = 10,/1- where c is the speed of light (300,000 km/s). (a) Find L(0.5c), L(0.75c), and L(0.9c). (b) How does the length of an object change as its velocity increases?
