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?
