What is the speef of the bomb after the push? What about the speed of the astronaut after the push? How much energy did the astronaut expend pushing the bomb away?

An astronaut (mass mA = 120.0 kg) is attempting to disarm a bomb (mass mg = 80.0 kg) in outer
space. They are both stationary.
After a little while, he realizes he can just push the bomb away and let it explode (Who's it going to hurt? Outer
space?). To get a safe distance away, the relative velocity between him and the bomb must be 10.0 m/s.
VB = ?
