5. According to an observer on Earth, two spaceships A and B are moving towards each other. Spaceship A is moving at 0.80c to the observer's left while spaceship B is moving at 0.65c to her right. An astronaut in spaceship A turns a laser on for an experiment. Relative to an astronaut in spaceship B, how fast are the photons coming from the laser in spaceship A travelling? Express the speed in terms of c.
