2. As seen from Earth, two spaceships A and B are approaching along perpendicular directions. Spaceship A is observed by an Earth observer to have velocity uy = −0.60c and spaceship B to have a velocity ux = −0.80c. Find the magnitude of the relative velocity of the two spaceships by transforming the velocity of one ship into the rest frame of the other. Remember, the answer has to be less than c.
