1. The problem statement, all variables and given/known data Two rockets leave their space station along perpendicular paths, as measured by a flight controller on the space station (see figure). The flight controller records the speeds of Rockets 1 and 2 to be 0.6 c and 0.8 c respectively. What is the velocity of Rocket 2 as measured in the reference frame of Rocket 1? Give both the components and the magnitude of this velocity Rocket one is going in the positive y direction and rocket 2 is going in the positive x direction. 2. Relevant equations 3. The attempt at a solution So I tried setting it up by using rocket 1 as the S' frame and rocket 2 as the S frame. The components of velocity are: S' = (-0.8c, 0.6c, 0) and S = (0.8c, -0.6c, 0). Plugging these values into the Ux equation, -0.8 + -0.8 / (1+0.64), but the correct answer is 0.64c for Ux. I also need to figure out Uy, but I think if you can help me solve for Ux, then I can solve for Uy myself. I appreciate all help, Thanks!
