A space vehicle is traveling at 3690 km/h relative to Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 95 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is the speed (in km/h) of the command module relative to Earth just after the separation?
