Question

PIA - Vi 62 GO In Fig. 37-28a, particle Pis to move parallel to the x and x' axes of reference frames S and S', at a certain velocity relative to frame S. Frame S' is to move parallel to the x axis of frame Sat velocity v. Figure 37-28b gives the velocity u' of the particle rela- tive to frame S' for a range of values for v. The vertical axis scale is set by u' = -0.800c. What value will u' have if (a) v = 0.80c and (b) v c? Fig. 37-28 Problem 62.
