Demand that the clock is not "pathological": ta = tb where a and b refer to the time between clicks when the clock is stationary, and moving respectively. Hence, (19) d = 1 - v 2 /c2 d 3 Carts on carts... Using the 1d velocity addition formula, vi+1 = vi + u ; c1 1 + vi u (20) Define i by vi = tanhi and by v = tanh. Then, tanh (i+1 ) = = tanh i + tanh 1 + tanh i tanh tanh (i + ) 4 (21) This implies i+1 = i + , v0 = 0 0 = 0. Thus n = n. Hence, vn = = = = tanh(n) tanh ntanh-1 (v) n...
