An observer is stationary in the inertial system S. A car is moving in the x- direction with speed v = c / √2 with respect to the observer in S. The driver of the car is stationary with respect to the car, and thus the driver is in a different inertial frame S′. The passenger of the car takes out a baseball, opens the sunroof of the car and throws out the ball with a velocity vB =c/√2. If the baseball is thrown in the minus x-direction (opposite to the direction the car is moving), what is the speed of the baseball as seen by the observer in S?
