Suppose in the figure that the origins of S and S' overlap at t=t′=0 and that S' moves at speed v = 1.80×108m/s with respect to S. In S', a person moves with a velocity whose components are u′x=u′y=1.15×108m/s .
What will be the magnitude of her velocity with respect to S?
What will be the magnitude of her velocity with respect to S?
What will be the direction of her velocity with respect to S?
