A 75 kg astronaut is in space fixing a satellite when you need to consult the repair manual. So, a second
astronaut throws the manual in a straight line towards the first astronaut, at 3.0 m / s
in relation to spacecraft. Astronaut 1 is at rest in relation to spacecraft
before grabbing the 2 kg manual. Determine (in relation to spacecraft) (a) the
speed of astronaut 1 right after grabbing the book, (b) the initial kinetic energies and
end of the book-astronaut system and (c) the momentum exerted by the manual on the
astronaut. (d) Finally, determine the speed of the astronaut, before and after
grab the manual, in the reference center of mass of the manual-astronaut system.
