An astronaut of mass 65.0 kg is at rest relative to her space vehicle with nothing behind her except the empty,dark, vacuum of space. Another astronaut decides to play a practical joke on her and throws a 10.0 kg anvil(because those are totally used in space) at her with a velocity of 3.00 m/s. How fast do she and the anvil moveonce she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicle
