In the figure shown below, frame S' moves relative to frame S with velocity 0.62c i while a particle moves parallel to the common x and x' axes. An observer attached to frame S' measures the particle's velocity to be 0.47c i. In terms of c, what is the particle's velocity as measured by an observer attached to frame S according to the (a) relativistic and (b) classical velocity transformation? Suppose, instead, that the S' measure of the particle's velocity is -0.47c i. What velocity does the observer in S now measure according to the (c) relativistic and (d) classical velocity transformation? (i is a unit vector) S S' -Particle u'as measured from S' ủ as measured from S -x'
